Pink supermoon

Pink supermoon

I always note that I’m not really an astrophotographer, and this is readily apparent to anyone who sees my shots, but I do occasionally like to take a snap just to prove I was there. Thus, here’s my photo of the full Moon of April 7, 2020.

There are those who call this the pink Moon, even though it isn’t pink, and a supermoon, which may be an exaggeration even though the Moon is excellent. I’ve read a few sources this morning claiming that we “often” call the April full Moon the “Grass Moon” or the “Egg Moon.” This may well depend on just how you define often.

The super bit comes from the fact that this particular Moon does appear to be slightly larger in the sky–about seven percent bigger than the average full Moon. That’s because the moment of fullness came when the Moon was near perigee, its closest point to Earth during its orbit around us.

For those into photo specs, I made this with a simple Canon PowerShot A530 pointed through the eyepiece of my 8-inch Dobsonian at 50x magnification.

The Moon will be pretty close to full this evening and almost as super, so check it out if you can.

Goldendale Sky Village gives amateur astronomers dedicated observing site

Amateur astronomers in the Seattle area have been dreaming of a clear, dark place from which to observe the heavens since the clouds rolled in and light pollution obliterated much of the night sky. Those dreams are coming true at the Goldendale Sky Village just east of that south central Washington town.

The Goldendale Sky Village (GSV) is owned by a limited liability company (LLC) of the same name, made up of members with interest in astronomy. The effort to establish the GSV is the end result of a search several decades in the making.

Most recently, the Seattle Astronomical Society (SAS) took a run at establishing a dark-sky observing site beginning in about 2005. Three years later, the project was tabled because the society couldn’t reconcile two desired criteria for the site: clear, dark skies and convenient proximity to Seattle. (I wrote about the end of the project for the April 2008 issue of the SAS newsletter, The Webfooted Astronomer.)

In 2016 Stephanie Anderson, a co-owner of Seattle’s Cloud Break Optics who was president of the SAS at the time, wanted to re-start the initiative and recruited SAS member Christopher Smythies, who is now the general manager of GSV, to head up the search.

Searching for the spot

“For two years I went out east of the mountains and familiarized myself with the land,” Smythies said. His focus was on two areas: Cle Elum and Goldendale. He found Cle Elum to be prohibitively expensive, and most parcels of land available for sale there were intended for housing and carried restrictions.

“Goldendale had a lot of attractive things about it,” Smythies said. “It was darker, the land was much cheaper, the rules were much looser, but it was further away.”

Smythies figures he must have looked at more than 100 properties over the course of a couple of years. By the time of the annual SAS Spring Star Party in May 2018 at Brooks Memorial State Park near Goldendale, he had a list of five of them for attendees to check out. The last of those that they visited is the one that is now Goldendale Sky Village.

“I immediately knew that was going to be it,” he said. “It was very remote, it was relatively flat, there were low horizons. It was pretty land; it wasn’t scrub land or pasture land, it was very attractive land with nice vegetation on it. And it was relatively cheap.”

“I thought it was perfect,” Smythies added. Unexpected bonuses include a line of sight to a communication tower that gives the site Internet access, and a great view of Mt. Hood to the west. There is federal land and open prairie nearby that will likely remain unoccupied, so future light intrusion isn’t a big concern.

LLC created for site

By this time the Seattle Astronomical Society had cooled to the idea of owning and operating a dark-sky site. Current president John McLaren said cost was a big concern. SAS would have had to do a major, multi-year fundraising effort or raise dues drastically to cover costs. Neither seemed likely to fly given the varying visions SAS members have for such a site. They considered trying to build a coalition with other regional astronomy clubs.

“That looked like it would be a legal headache,” McLaren noted. Running the site also would have created administrative tasks, including IRS reporting, that would have placed a burden on the club. The SAS board opted out.

“At that point, I decided to go another route to form a private group of people, an LLC, and then make it available to the SAS later on,” Smythies said. In June he put out a call for possible investors in the site.

“Within six weeks, two of which I was on vacation, we had 21 people saying ‘I’m in,’” he said. Smythies believes that a turning point for the project was when Anderson and Cloud Break Optics co-owner Matt Dahl signed on.

“She and Matt have such a good reputation for being kind of the hub of the astronomy community because of Cloud Break Optics, that once they said they wanted to be a part of it it was like a stamp of approval and everyone else piled on,” he said.

Original members paid $1,000 per share in the new LLC. That entitled them to use of their own 2,500 square-foot parcel within the village. They sold more than 100 shares and by the end of July had the cash to buy the land. The purchase became final in September 2018. Since then they’ve made improvements to the road into the property, created parking space, and moved “a billion” rocks and boulders to create a smooth place for the village’s central telescope field, known as “The National Dark-Sky Portal.” They’re planning for improvements that include a big tent, the Red Light Lounge, for sharing refreshments and shelter from the elements. Work this summer may include bringing electricity to the site as well.

It takes a village

Smythies says the village aspect of the GSV is vitally important.

“I wanted to put together something where people have lots, sure, but then there’s common areas right in the middle where they put their telescopes out and they observe together,” he said. This differs from some large astronomy communities where people might build a home on a two-acre plot. “Goldenndale sky village is all close together to promote the community atmosphere and the learning.”

While the GSV is a private company they intend to invite guests often. They hope to be ready by this year to host the SAS and its spring and fall star parties, and would like to build a similar relationship with the Rose City Astronomers in Portland, which is actually closer to the site. Smythies dreams of an astrophotography school and other educational efforts at the village.

The SAS hasn’t given up on creating observing sites. McLaren, who is a member of GSV, said SAS members also crave a dedicated site within 30 minutes of the city and one perhaps in the Cle Elum or Ellensburg areas, that might offer better observing conditions and still be relatively convenient. He hopes the Goldendale Sky Village model can be a good template for creating more observing sites.

“That would be awesome if it happened,” McLaren said, “and if some day astronomy clubs were able to negotiate access to all three locations that would be amazing.”

Smythies says there is room for perhaps 60 to 70 members at Goldendale Sky Village. The current price to join is $2,500 per share with a minimum of four shares. You can check out the site at an open house on March 21. Contact Smythies if you’re interested.

Sun streak ends! Whither Mercury?

All good streaks must come to an end, like Joe DiMaggio’s 56-game hitting streak or Cal Ripken, Jr.’s consecutive games-played record of 2,632. This morning Seattle Astronomy‘s personal mark of successful astronomical observations of Sun-related events was snapped at a modest four when we failed to spot Mercury during its transit across the face of the Sun.

Waiting for Mercury

Hope of spotting Mercury remained alive until the bitter end. I arrived at Seattle’s Seacrest Park just before sunrise when the transit had already been under way and below our horizon for a couple of hours. We got a few glimpses of the Sun during the morning, most not enough to register even a glimmer of light through properly filtered optics. Then came proof that Mother Nature can be cruel and sadistic, especially to those who would practice astronomy in Seattle. With the transit slated to end at about 10:04 a.m. PST, the clouds parted a bit at about 10:02, setting off a mad scramble to point, focus, and look. I thought I caught the barest edge of Mercury leaving the disk of the Sun, but I couldn’t be sure. There were lots of clouds in the view. The Sun was there but Mercury, true to his fleet-of-foot reputation, was gone. I count it as a nice try.

Not everyone who came to our viewing event was skunked. Seattle-based Associated Press photographer Elaine Thompson caught this shot during a brief clearing:

It pays to be prepared! The day was not a total loss. Many folks enjoyed a look at the Mercury-free Sun after the transit, a nice woman named Liz brought some Top Pot donuts to share, and hanging around at the beach waiting to spot Mercury with some new friends was not a bad way to spend a Monday morning.

I’d successfully seen four recent Sun events: the August 2017 total eclipse of the Sun, the Mercury Transit in May 2016, a partial solar eclipse in 2014, and the transit of Venus in June 2012. Off to start a new streak.

There will not, however, be another Mercury transit until 2032, and not one visible from North America until 2049. See you down at Seacrest Park in thirty years!

Mercury transit tomorrow!

The weather forecast is decidedly iffy for folks in Western Washington to view the transit of Mercury across the Sun on Monday morning, November 11. But a number of groups, including Seattle Astronomy, are planning to be out and waiting for breaks in the clouds in order to catch a glimpse of this relatively rare astronomical event.

Transit of Mercury

Typically there are 13 Mercury transits visible in any given century, and there will be 14 of them during the 21st Century. We last had one visible from Seattle just over three years ago, in May of 2016. Tomorrow’s will be the last until 2032, but that one and the next won’t be visible from North America. Our next chance to see a Mercury Transit from Seattle will be in May of 2049.

Thus we’ll be down at Seacrest Park in West Seattle near the Water Taxi dock in hopes that we won’t have to wait 30 years or travel halfway around the globe to see Mercury in transit. We’re aware of a handful of other viewing opportunities tomorrow in the Northwest:

Watch our calendar page for others; we’ll add them if we hear about them for the rest of the day.

There are a couple of things to consider when viewing the transit. First, the requisite warning not to look at the Sun without eclipse glasses or a properly filtered telescope. Second, you’ll not likely see Mercury without some magnification; it’s pretty small. Third, don’t try to use eclipse glasses with a telescope or binoculars; the equipment itself must be properly filtered or severe eye damage will result.

Alan Boyle of Geekwire has a good article about the 2019 transit that includes some links for viewing the event online should our weather fail to cooperate.

Jacobsen Observatory resumes open houses this week

TJO

Spring has sprung, and one of the many wonderful manifestations of that is the resumption of bi-monthly open houses at the University of Washington’s Theodor Jacobsen Observatory. The first of the year will be held beginning at 8 p.m. Tuesday, April 2. Future open houses will be held on the first and third Tuesday of each month through September.

The day of the week is a change. The open houses have been held on Wednesday evenings ever since we can remember.

The open houses typically include a couple of astronomy talks by UW students. This week Aislynn Wallach will talk about The Future of Telescopes and Aleezah Ali will discuss Binary Stars. Unfortunately, reservations for these free events are usually snapped up pretty early, and the April 2 event is already listed as full. The observatory classroom in which the talks are held only holds 45 people. You can check out future topics and make reservations on the TJO website.

Volunteers from the Seattle Astronomical Society staff the observatory dome on open house evenings and, weather permitting, give visitors a look through the vintage 1892 telescope, which has a 6-inch Brashear objective lens on a Warner & Swasey equatorial mount.

Total lunar eclipse visible from Seattle

Seattle astronomy buffs are downright pessimistic about seeing celestial events, even those that happen during our good-weather months. (And we have them.) Thus in the week before the total lunar eclipse of January 20, 2019, I posted this on the Seattle Astronomy Facebook page.

Amazingly enough, at about mid-day on eclipse day the clouds actually did begin to part a little, and a check of the Seattle Clear Sky Chart revealed a prediction that we’d have just 30 percent cloud cover come eclipse hour, and that it would be downright clear late in the evening.

One learns not to trust these things, but when the full Moon actually got up above the trees and into a clear sky out back of Seattle Astronomy headquarters, I decided this was going to happen and hauled the telescope out of the basement and onto the back deck. As the eclipse began I snapped a quick photo in order to express my amazement.

I am not an astrophotographer, as people who evaluate the entries for the Seattle Astronomical Society‘s quarterly photo contest always remind me. This one was shot with my smartphone, though when using it with the telescope I find it devilishly difficult to get the proper aim through the eyepiece (must pick up one of those gadgets from Cloud Break Optics soon.) My other “astro” camera is an old Canon Powershot A530, which is pretty easy to just stick up to the eyepiece and shoot.

I used the phone to get a pretty OK, if somewhat pixellated, pic at totality, too.

Interestingly enough, I found that the color of the “blood Moon” wasn’t quite so pronounced through the telescope and camera is it was in my naked-eye view. I think the magnification diffuses the color a bit, and the camera isn’t really made for that sort of work.

Even my sweetie, who is not normally prone to looking through telescopes at night in January, or any other month, for that matter, went out quite a few times for a magnified look, and we both spent most of the eclipse watching from a warm environment inside behind the glass of the French doors.

I hope you got a chance to see the eclipse wherever you were. The next one visible in Seattle will happen in May of 2021.

I looked through a telescope the other day

The weather gets to amateur astronomers from Seattle sometimes. I had several conversations at the Seattle Astronomical Society’s annual banquet back in January with attendees who, like me, fessed up to not doing much observing these days. It’s so cloudy so often that we tend to forget about the telescope, waiting patiently in the corner down by the door to the wine cellar. So it was fun on a string of clear evenings recently to get out and get some scope time.

I even announced it on Twitter.

The views of Jupiter on that night were a little murky, though the Great Red Spot occasionally popped into sight as plain as the cyclone on your face. The next evening seeing and transparency were about as good as they get in West Seattle, and I enjoyed some of the best views of Jupiter I’ve ever had.

I also took a look at Saturn, which was at opposition June 27, but on that evening it was still awfully low in the southeast sky and thus looked pretty fuzzy. I’m looking forward to some better views of Saturn as it comes around a little earlier in the evening each day. I took a few peeks at Venus, too.

While Jupiter and Saturn are among my favorite observing targets, the big show of the summer will be put on by Mars. The Red Planet will reach opposition on July 30, and this particular apparition will be an outstanding one. Mars will be the closest it has been to Earth since 2003, which was its closest approach in 60,000 years! It was that event that pushed me to get more involved in observational astronomy. This summer we’ll have great opportunities to see surface details on Mars.

As I write this, at 1 p.m., it’s looking pretty clear outside, though some clouds are in the forecast for the early morning hours. I shouldn’t even think this, lest to jinx clear skies, but I think I’ll get out again today and see how Saturn is looking.
