Lunation 1038
      #1260650 - 11/20/06 11:40 AM

We have attempted at least a few times, here in the Lunar Observing Forum, to hold coordinated observing sessions based on a particular day of the lunar cycle or a specific lunar region or feature. Because so many of us are clouded out, or crowded out by schedule conflicts, on any given day these observing sessions have never really gotten off the ground. So we're going to try a different approach for Lunation 1038, which begins following today's New Moon.

For the duration of this lunation - and for as long afterward as seems relevent - this thread will be open for the posting of observing reports, images, sketches, and responses to those reports. Reports of observations can be as simple as when you first (or last) glimpse a crescent Moon, or as elaborate as a detailed description of what shows up especially well along the terminator the night you observe. Write it in whatever posting style suits you. This is not a contest and there will be no judgements passed. If you thought Copernicus looked really cool and that's all you have to say, that's your report. If the Moon inspires poetry or you want to simply list features you identified, that's fine. But best of all, if you can place the features you observe in a geologic context, we will all learn something. So consider doing a bit of homework along the way, and sharing what you dig up. Whatever works for your style of observing, so long as you observe and post a report.

We do ask that, however you make a report, start out by listing the gear you used (telescope size and type, eyepieces and magnifications, filters, etc.), the seeing conditions you encountered, the time of the observation and the date, and where it was on this good Earth from which you made the observation.

Images and sketches are welcome additions to this project. If they accompany a report it might be a good idea to post them in the Member's Gallery and include a link to them in your report, but so long as they fit our image posting guidelines (need to be kind to those of us - like me! - who are using dial up) images and sketches may be included in the post directly. For images and sketches, give us some information on the type of equipment and technique you employed in addition to the information requested above, but please don't make your report about the image. Use the image to illustrate your report, or allow the image to speak for itself - something the best of them do so very well. And should you also post such pictures in their respective specialty fora for discussion with the experts there, please include a link to that discussion in your observation report so interested parties can easily follow up on the matter.

The hope here is that by casting a month-wide net, somehow between the bunch of us we'll pull together enough material to create a thread worth adding to the "Best of the Lunie Bin," from which future members can access it and learn something about lunar observing. If we do this right, it might even inspire others to turn their telescopes and binoculars toward the Moon.

And if it works really well, we'll do it again!

It sounds like a nice idea... I'll be happy to participate.

However, how is this number 1038 assigned to this lunation? I've never personally seen lunations numbered like that before.

Here's a brief conversation we had on the subject a while back. Lunation Numbers

Wikipedia's notes on Professor Brown: Ernest William Brown

I haven't been able to find a lot more than that, although I will from time to time come across other people using this numbering system to keep track of lunar observations. It's arbitrary, but given the fact that a lunation doesn't usually fit entirely within a calendar month, I find it easier for my own record keeping purposes.

It's been well over a year since I last tried to uncover the origins of this numbering system. If someone who has joined us since then has something new to add, this would be as good a time as any.

      #1265053 - 11/23/06 12:04 AM

Shortly after sunset this evening I stepped out to see if I could catch a glimpse of the Moon. It was very low, perhaps six to eight degrees above the horizon, set against a pale blue band of sky with darkness above it, and framed by banks of clouds that were sooty gray with faint reddish tints along their lower edges. It was a beautiful and compelling sight, but not one that lasted long. The light faded from the sky, the clouds darkened and then became invisible, and the slender crescent Moon slipped below the roof lines of the houses southwest of me. A very short first act. Or should I say a prologue?

My wife and I were traveling home to Phoenix from Cave Creek (north of Phoenix) last night marveling at the beautiful sunset (oranges and blue grays) and the tiniest sliver of a moon. I have a brand new StarMax 102 I haven't used yet so maybe tonight's the night. That is if I can waddle away from the dinner table and it's clear tonight. John

friday evening , 11-24-06 , 4.25 day moon.
Equipment used: 80mm binos at 19x
Mare crisium was easy as was part of mare tranquilitatus.One crater stood out but I didnt know what it was until I checked the sky and telescope moon map, and I now beleive it was probably Hercules.
Mare fecunditatis was visible slightly below tranquilitatis, also part of mare nectaris was coming into view about half in and half out of the sun light.
There was a lot of structure to the terminator ,but most of it wasnt easily seen in binos, or at least none stuck out enough fro me to remember.
Tomorrow clear skys willing Ill break out the 80mm scope.

It was Friday 11-24-06. Bone colored, the slender *4.14 day crescent Moon, setting into the early evening twilight, was framed by the deepening gray of incoming cloud banks and a dense grove of eucalyptus trees to the southwest. Telescopes or binoculars were out of the question due to a quickly clouding sky, so a simple naked eye observation would have to do for me tonight. It was easy to see Mare Crisium's circular form taking a bite out of the thin bow about one third of the way down the terminator from the north. The highlands to the south gave the terminator a less sharp edge than in the north or at least that is the way it appeared to me. The Earthshine had not been fully quenched, and it still glowed subtly, a ghostly globe above the horns of night. I watched it for five minutes or so, until a veil of cloud obscured my view.

*edited: was 4 1/4 days to 4.14 days

      #1268314 - 11/25/06 12:08 PM

I was just getting into my truck last night around 2330 UT (Nov. 24) when I noticed the moon.

Lunation 4.05
Altitude 13 deg .08'
Az 217 deg .16'
Illumination 16.8%

The lighted sliver was bursting out of the shadows as if there wasn't enough room within the lunar disk to hold it. Earthshine was bright enough to make out several darkened features with naked eye. What impressed me most was the appearance of a thin line of light completely circling the limb around the Earthshine, almost looking like a lunar eclipse.

By the time I got home, the moon had disappeared behind the trees, so I did DSO observations instead.

I just noticed the difference between my lunation and Rich and Andy's. I'm a bit confused and am wondering if I'm overlooking something. My VMA program was set correctly with the time change for Ohio at -5 hours and I had the date and time correct (2006 11 24 at 18:30 EST). Anyone have a clue what I might be doing wrong?

Thanks Mardi, but that's correct as well. Maybe I'll check another source or upgrade my VMA program to see if there's a glitch there.

Erika Please forgive me! I have mistated the lunation. It was more accurately a 4.14 day old Moon. I apologise for the confusion, I was only quessing at an approximate lunation since this was a naked eye observation and I didn't have my laptop with me at the time. (But hey what's .11 days among friends anyway? )

I used the lat and long for ashtabula, which is 18 miles west of me, could that be it????
I also made sure the time for vma was correct, as far as I know.

At least you can see it sometime...

I've been doing well to catch glimpses now and then. But then, that's why this thread is set up as it is. I can't make observations this even, but some of you might.

Saturday 11-25-06 5:41 pm EST.
Lunation 502 days (according to my VMA)
Equipment used 80mm refractor , 25mm(34x) and 17mm (50X), the sky was to hazy to allow more mag.
in the upper left hand side was Atlas and Hercules, two legendary strongmen.Slightly lower down was Posidonius.
Further down yet right on the terminator was Theophilus.
Theophilus is the lead crater in a three crater chain that also includes Cyrillus and Catherina, neither of which was veiwable at the time of this observation, but should be well out tomorrow night.
Thats all I was able ot do, as the haze got a lot worse after I got started.

Friday 11-24-06
Equipment: 60mm refractor, 20mm(17x)and 10mm(35x) eyepieces.
Only had a few minutes between good dark and the moon moving behind the trees. The most notable thing I noticed was the earthshine. Very bright (for earthshine!).

I started early before dark set in. I got one usable picture of the moon. This I will study and report what craters I could see. I also had several young people stop by. Telling me stories of the neighborhood. To keep them busy while I set scope up I gave them my spotter scope. The sky was clear with some clouds. I was out there from 3:30 till 5:00. I used my 8 inch reflector with a 25mm and a 15mm lens. I also used my 2x barlow on both. I tried my moon filter but it made everything too green and dark to improve on the view. I could see many small craterlet on the mare. After studying the photo from tonight I will tell which mare.

Sunday 11-26-06 5:35 EST , Lunation: 6.01 days (according to my VMA).
Equipment used: 80mm refractor at F/11.3 , 25mm kelner (34x) 17mm plossl (50x) and 12mm plossl (71x).

My first look astounded me ,because Aristoteles and Eudoxus were literally right on the terminator.Eudoxus was really cool as it was simply a black pit, but ti had white dots of light most of the way around it, and for all the world ,reminded me of a stone henge on the moon.
To my amazement between the two craters was another crater(????) yet neither VMA nor the Sky and Telescope moon map show a crater there???? possibly a depression between the two which at this angle gave the impression of a crater????.
Tonight ...all three of the crater I mentioned last night came into viewalong with Rupes altai(altai scarp).
Useing the 12mm , which was as high a mag as the atmosphere would allow tonight, I stopped for a few minutes on the spot were Apollo 17 landed and wondered if we would ver return there,for some one my age who remembers the space race,this isnt to hard to do.
Im going to include a photo that will show the non-existant crater between Aristoteles and Eudoxus.

Now before any one says anything , I know this image is bad, Im only includeing it so yall can see why I thought there was three craters where only two exist.

edit 2 :after going through my pics from last night and doing a lot of cropping and enhancing I came up with is photo which really shows the non existant crater much better.

Andy I a glad you posted the photo, now I don't have to put my bad photo up. I think if my observation are correct I could see craters Theophilid, Cyrillus and Catharina. In my raw image I could see little pits which I call crater lets on Mare Nectaris.

Lunation 1038, Day 5 : Atlas and Hercules

Widely regarded by many as one of the most beautiful crater couples on the Moon, 87 km Upper Imbrium aged Atlas on the right and 69 km Eratosthenian aged Hercules to the left make an odd couple indeed. According to Chuck Wood, "The Modern Moon" page 72, although Atlas is older than his strongman brother, he apparently has fewer secondary craters than his younger sibling. Furthermore, the floor of Hercules is relatively flat with a couple of small hills protruding through what appears to be a somber floor of lava. Measuring just 13 kilometers across, little Hercules G seems the only major disruption to it's smooth floor plain. On the other hand, Atlas has a floor that is covered with various terrains. It displays the characteristics of a FFC (a Floor Fractured Crater). Along the periphery of the floor rilles snake around it's offset circular ring of central peaks. There are large darkened spots on this floor as well, these are thought to be pyroclastic deposits that were implaced as a result of giant lunar fire fountains fed by these same rilles. Ejected violently from the rille, dark, spherically shaped, glass beads were thrown several kilometers by the force of these eruptions at several locations along their circuitous path. They settled onto the rough surface, and in places close to the rilles, these layers are 10 or more meters thick. Due to the relatively weak gravity of the Moon, these beads are hurled far and wide settling as a fairly even blanket over very large areas. Both craters have a wide and prominent glacis, though Hercules appears a little less eroded.

As I've discussed before, I've been comtemplating combining sketching and high resolution imaging in the same sessions. Forgive me for the low quality of this image of Atlas and Hercules. I had started my sketch at 1:05 UT and finished at 1:55 UT, however, the Moon had dipped lower into the western sky and though the seeing was Antoniadi III when I started, it deteriorated to Antoniadi IV by the time I started to record my avi's of the area. Consequently there were few usable frames from which to create a good stack for further processing. I'm still learning to do this but I'll try to improve in the future. When the Moon is imaged at a higher elevation above the horizon, I think I'll get better avi's. The image was taken between about 2:15 UT and 2:30 UT.

First the sketch and the sketch details:
