Supermoon With a Super Eclipse

The Astro Babes were together watching the mosquito-filled eclipse Sunday night. We watched the Moon darkening over the bay of Green Bay, which added a whole new dimension to the eclipse. The moonlight was very bright and sparkly on the water when we first arrived at the beach, but the reflection also faded with the Moon until it also disappeared.

Although we originally had planned to complete the requirements for the Astronomical League’s Lunar II observing program, we had been promised a solid wall of clouds all night so weren’t prepared when the skies cleared and the eclipse was in full swing. Thanks, weather guys.

Yesterday we heard from our fellow club member Rodrigo. Once again, he compiled a great montage from Sunday’s total lunar eclipse over Wisconsin. Thanks for sharing, Rodrigo!!

Moon Eclipse 9-27-2015 low

Here’s what Rodrigo had to say about his amazing picture:

This one is a composition of different times (20 min intervals) from 8:00 pm to 10:50 pm. The pictures are exposed to match what I saw naked eye. So some of the faces are actually HDR of the moon shoot so the bright portion is not overexposed (moon #4 and #8). I used my Orion 80mm and tracked with my small Meade LXD 75 and Canon no mod Xsi. The first portion was between 1/400s and 0.3″,  ISO 200 and Totality was 8s ISO 200, and then I used ISO 400 and cut the exposure to 4″ due to the wind.

Supermoon Eclipse!

Finally!! A celestial event that is both at a reasonable hour and visible from home. How often does that happen? I’m of course talking about the upcoming total lunar eclipse! I think Universe Today said it best by calling it the “Super-Harvest-Blood-Moon Total Lunar Eclipse.

So let’s start with Super. The moon’s orbit around the sun is elliptical, not circular. This means that it’s not always the same distance from the earth. On Sunday evening it will be at what is called Perigee, or at its closest to the earth. It will appear about 14% bigger than at other times.

Next up – Harvest. The Harvest moon is simply the closest full moon to the Autumnal Equinox which is when day and night are each about 12 hours long and the sun rises exactly due east and sets exactly due west. This was September 23.

Now the creepy – Blood. I have to confess  – I don’t really know much about this term. It has something to do with prophecies and apocalyptic whoo ha and frankly if you really want to know more about that you’re on your own!

And finally the big one – Eclipse!! This occurs when the sun is opposite the moon, and the moon, earth and sun are lined up so that the moon will pass through the earth’s shadow, temporarily blinking it out. The shadow has two parts, the Penumbra which is the dimmer outer shadow, and the Umbra which is the darker center. The moon will pass through both the penumbra and the umbra during this event.

Hopefully Lynn and I will be watching and recording all the necessary contact information and feverishly making sketches for our Luney II observing program. Or maybe we’ll just kick back in our lawn chairs and enjoy the show. Either way – it should be a great show!

Amazing Photos From the NNSF

Milky Way at NNSF

Check out these aMAZing photographs from last week’s Astro Babe trip to northern Minnesota and the Northern Nights Star Fest.

These pictures were taken by a super-talented member of the NPMAS astronomy club here in Green Bay. Rodrigo takes some of the best astronomy and aurora photos around, and we’re very lucky to have his talent, his helpful attitude, and his friendly smile hanging around our club. If I ever get a decent camera, he’ll be one of the first people I turn to for help getting started.

In Rodrigo’s notes, he said he finds the Wolf’s cave nebula, pictured below, a very interesting object. In addition to the dark and reflection nebulae, he said that you can see an old planetary nebula towards the bottom of the picture about six o’clock, and some faint supernova remnants near the reflection nebula.

Rodrigo said that the aurora’s that we saw Saturday night at had a lot of deep blue and violet color, which means a nitrogen emission. He said that he hasn’t seen very much blue in his other aurora pictures in the past, so these photos are a nice addition to his aurora collection. In the aurora pic to the right, you can also see the Andromeda galaxy.

Thanks so much for letting us share these photographs with all our Astro Babe fans, Rodrigo!!

Another Star Party in the Can

Even though I’m late in posting this, rest assuredMAS-logo that the Astro  Babes did make it safely home from the Northern Nights Star Fest Sunday night.

The heat stayed with us for the remainder of the star party, but there was dew relief on Saturday night due to a light breeze. We were also treated to some amazing auroras around 11 p.m. Some of our club members took pictures, and I will post one as soon as I can get my hands on one.

We were also treated to lots of lightning that flashed behind the trees at the south end of the observing field for at least an hour. We had originally planned to cover our equipment with plastic and load it up in the morning, but when it looked like rain and storms were zeroing in on us, we joined everyone else and packed up the car in the dark. We headed back Sunday morning.

We had some observing successes, each earning an observing certificate for bagging 15 objects, plus lots of cool peeks into huge 25″ and 30″ Obsessions. And the Minnesota group are great hosts and fun to hang out with and share our love of astronomy. I feel we’ve made a few friends there.

Already looking forward to next year, but crossing fingers that the heat won’t be there to greet us again. Five days of temperatures near 90 and no air conditioning is not for the faint of heart!

Another Soggy Night

Friday was another day filled with astronomy, humidity, dave-faulknerand excessive heat. Ninety-one Fahrenheit with a dew point in the low 2,000’s. So of course you know what THAT means. Dew, dew, dew!

The Northern Nights Star Fest has been a challenge for Amy and me, although the skies have been mostly clear. Last night we again abandoned the 8” club scope and the 20×80 binoculars because they only seemed to work with the hair dryer blowing constantly. Guess it’s time to break down and do something about dew heaters. It’s been really, really frustrating for us.

But fortunately, there were over 60 telescopes of all flavors and sizes on the observing field (WITH dew heaters) and we got to see some pretty incredible stuff. I saw the Andromeda galaxy naked eye for the first time, and that was exciting.

Another of my faves (although hardest to see) was Stephan’s Quintet, a group of five faint galaxies in Pegasus. Four of them are in a cosmic dance. I’ll warn you though, even in a 30” Obsession they were pretty hard to make out. I also got to see Jacques comet in the 30”, tail and all. How cool is that?

Amy loved Draco’s Cat’s Eye Nebula in Kevin’s 18” Teeter. She said it had a turquoise jewel-like center that was very cool. She also renewed her interest in radio astronomy and is now talking about trekking out west to the Green Bank observatory.

Lots of astrophotography lectures yesterday and today that we played hooky from since we don’t have any fancy cameras or processing software. Maybe we’ll get to that hobby later.

Star Party Time

Despite two harrowing near-misses and a wrong exit in Duluth, the 20150813_154840Astro Babes safely rolled into Palisades Minnesota yesterday for the start of the Northern Nights Star Fest. Unfortunately, we got clouded out on the first night, but we weren’t complaining because we were both snoring by 9:30.

Today was the first day of organized programs. First, we heard a lecture by Dave Falkner, a NASA/JPL Solar System Ambassador and former president of the Minnesota Astronomical Society, our host club. His presentation was about the 2004 Mercury’s Messenger Mission to learn more about how our Solar system was created. Research included studying why Mercury’s iron core is so large and so dense, as well as understanding Mercury’s unusual magnetic properties. The mission ended in a decayed orbit in 2012.

The next presenter was a fellow club member, Kevin Nasal. He had recently bought a Teeter’s 18” truss-tube Dob telescope, and he shared his comparisons with an Obsession telescope of equal size and quality.

Following that, a group of us got some training on how to use the MAS’s 25″ Dob. The training was interesting, but it was so hot and humid out in the observing field that it was hard to focus. And I won’t even mention the pesky, angry bees who lost their home in the observing field yesterday and are still buzzing around looking for revenge. Good thing they sleep at night!

Tonight we’re expecting clouds and possibly rain again, and the plan is to just to hang out, maybe watch a movie with the group, and get ready for tomorrow and Friday nights’ clear skies.

Star Party in Amberg

A great time was had by all at Gerry’s star party scheduled spider-pixThursday through tonight in Amberg, WI. A small group turned out on Thursday, but Amy and I were lucky enough to catch the best skies on Friday night. Tonight (Saturday) was clouded out.

Yes, there were misquitoes and flies, but Deep Woods Off took care of them. This spider, however, looked big enough to grab the Deep Woods Off can and chase us around the observing field. At least we didn’t have to battle any dew.

The skies were unsteady around 10:30, and thin clouds occasionally interfered briefly with what we were trying to observe. But as the evening progressed, seeing steadied and I found M4 and M5, and easily split Alcor and Mizar with Gerry’s 10×80 binoculars. We saw Pluto in Gerry’s 10″ Schmidt, watched a really bright Iridium Flare, and the Milky Way brightened as the sky got darker.

Amy and I also entertaiobserving-fieldned ourselves by looking for Asterisms, and found the Engagement Ring, the Owl Cluster, the Gas Pump, and the Guardians of the Pole. We’ll write more about Asterisms in a later blog.

Oh yes. I can’t forget to mention the Twizzlers and the Banana Cream Pie from the Amberg Pub. Thanks Gerry and Mary!!

Clouds Didn’t Rain on Our Parade

The Messier Marathon last weekend was tons of fun. It’s always great to get together with

The Messier Marathon seems to bring out the foodie in all of us.

others who share your passion. And although we amateurs often gather in groups to observe, there’s not always a lot of social interaction going on.

And that’s why I like the Marathon. When it is clear, you can observe all night long, and when it’s cloudy, you can hang out socially with people you like. It’s a win-win either way.

This year it was clear at sunset. As it got dark, I piddled much of the first hour away noodling with the finder scope and getting things polar aligned. Luckily, Amy distracted me by finding Messiers with her binoculars. If it had’t been for her, I would have missed it all because, about an hour after it got dark enough to observe, the clouds rolled in from the West and stayed for the night.

Just a few of the telescopes ready for a night of observing at the Brillion Nature Center.

Inside the shelter, there was talk about moving the Marathon up until early April next year, but in April you’re wrestling with dew all night long, and that can be really frustrating too.

Eh?? Which way is North???

Had a great time though. Got to hang out with Amy, ate lots of treats, scored a chunk of Fran’s Oreo tort before it was gone, got skunked in a Cribbage game with Amy, Jim and Wayne, got more practice polar aligning the telescope, and got to bed early. It was a good night.

Jupiter Triple – Check!

Here's a bad selfie of me with the three shadows on  Jupiter.
Here’s a bad selfie of me with the three shadows on Jupiter.

Ok – so a clear night and a telescope would have made this a bit more satisfying, but hey, we can’t have everything!

On the night of the triple shadow transit we were, of course, clouded out. We weren’t alone this time, practically the entire U.S. was under a blanket of clouds. So that’s where we went – to the cloud! If we can’t watch a live transit, we would settle for a live webcast of one.

Yay Griffith Observatory! They came through with a promise of a clear sky and a live broadcast. I tuned in, made sure Lynn was online too, and made myself comfy on the sofa. There were over 1400 people online, and the comments were streaming so fast that I could feel the excitement! Plus, I was sharing this experience with people from all over the world!

Then Jupiter came into view. Well, the hazy blob appeared on screen. It seems that high altitude winds were making the view unstable. Fortunately Lynn was quicker than I was when someone posted an URL for another live webcast from Brazil. She texted me the new site and we both switched to Brazil.

Jupiter was setting there, and the sky was clear! Perfect! By now I had moved to the recliner, and had hooked up my TV to act as a monitor, thanks to Lynn for the idea. Why can’t all observing sessions be this comfy?

As the shadows crawled across the face of Jupiter, I was transfixed by the image. Checking this rare event off of my ‘must see’ observing list completed a very hectic week for me. Sure it would have been nice to be peeking at this through the eyepiece, but sometimes we have to take what we can get.

So here’s your lesson for the day, when a rare astronomical event is clouded out, somebody somewhere will be showing it on the net. You gotta love technology.

Make Mine a Triple

We are so clouded out here in Wisconsin that it’s not even funny. And then, to crush any hope that we have of watching the Jupiter triple tonight, it starts to snow. One look at the satellite map on Weather Underground sealed the deal. No observing of the triple for Amy and me tonight.

However, we’ll be glued to the Griffith Observatory feed with all the rest of the clouded out saps in the country. Show starts at 8:30 p.m. PST. Be there or be square!

If you are one of the lucky ones to watch the transit tonight, or just want to share your thoughts about the live feed, share them with us!

During our last weekly meeting, it became apparent that Amy and I are getting excited about the upcoming triple transit of Jupiter this Friday, January 23rd. The transit:

  • is going to be at a reasonable hour that will not require an alarm clock
  • temperature promises to be above zero (probably into the double digits at transit time)
  • will happen on a Friday night so there’s no worry about getting up for work the next day
  • event has the word “rare” in it

All this scenario needs is a clear, dark sky and we’ll be happy.

Amy and I have witnessed the transit of Venus, and I think we may have seen a double transit at some time because they are pretty common.

But a triple, with the shadows of Callisto, Io and Europa visible on the surface of Jupiter at the same time, well, that doesn’t happen very often. In fact, it averages out to just once or twice a decade. Jupiter’s equator and the orbits of these three big moons will be almost edge-on to our line of sight, which only happens twice in Jupiter’s 11.9-year orbit of the Sun.

We’ll be doing some planning during the next few days, calling Tony and the other big club telescope guns to see if anyone will have something impressive pointing towards Jupiter that night. For this event, the bigger the better holds true. It will be a great opportunity to take some pictures and see something that most people never witness. Find a club or a big scope and get out there! As I said, all this scenario needs is a clear, dark, sky and we’ll be happy. Extremely happy.
