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!!
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.
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!
The picnic started at 6:30, and we were lucky enough to dodge the rain that had been predicted for picnic time and into the night. It was muggy, sticky and just generally unpleasant out there today.
However, despite the humidity hovering in the mid 90’s, we still had a great time.
Amy and I left around 8:30, when Dick was setting up to show some amazing weather videos that Tony took at the Nebraska star party.
We already saw them when we were at the Minnesota star party. Plus, it was getting late on a work night, and we’re pretty whimpy. Yawn!
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!!
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!
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.
Despite two harrowing near-misses and a wrong exit in Duluth, the Astro 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.
Don't worry the scope is in there somewhere! Minnesota star party here we come! pic.twitter.com/gHN40FsDPN
