Goodbye Ylog, Hello, GlennFrazier.com!


I recently received an email from someone who noticed that it's been years since I posted to Mac's [Astronom-] YLog hear at ylog.blogspot.com. They asked if I would be willing to give up the URL. I suppose it's because their first name begins with the letter "Y".

Anyway, friendly netneighbor that I am, I of course agreed. So I've cleaned up the archives, and I'm making this last post, and then I'm transferring it all over to my main blog, GlennFrazier.com. All future (if any!) astronomy blogging I do will be done there...until further notice, of course.

Actually, I'd like to get back into it. I've moved from the Philly suburbs to just outside Pittsburgh, and I've now got a little less light pollution from my new yard. I haven't had any scope time, yet, though. We'll see, I suppose. I certainly miss it...

Anyway, see you over at the new address!

Tempted...


Tempted...

I really need the sleep, but astro-forecasts say if I stay up to 2am, the skies will stay clear of clouds and seeing/scintillation will improve from "poor" to "average", although transparence will drop to "average" from its current level of "above average".

No, I'm going to sleep. Hopefully I'll get time to scope out the Jupiter-Venus event. I naked-eyed both of them as they slipped down behind some trees this evening, but I'd really like to put a scope on Venus (which would be a first for me). And no, I did not catch the five planet super-show last month!

Ah, well.

Finally!


Finally!

Despite the fact my binocs are dirty, depite the fact my Dob needs collimating, despite the fact that both neighbors' porch lights were going on and off...I finally got some good time under the stars, tonight!

It was a short stint. Took awhile to get oriented, as it's been something like four months since I've sat at a scope. Darn babies. Darn weather. Darn need to sleep.

Anyway, I started off with M13. It was my first time, and it kinda surprised me when I just aimed in the general spot, glanced through the big 32mm andå‚­ang! there it was, all big and globby. Seeing wasn't great, but at higher powers I could make out some graininess. Showed the wife; it was her first time, too.

I then decided to look up the Ring Nebula, and found that pretty quickly too. Seeing was terrible, as it was a straight shot right above my house's roof and under high power there was a lot of waver. Tried it with and without the broadband filter for the heck of it; better without this time. Again, grabbed the wife to show her; I'd seen it before, once, but it was her first time. She had a hard time keeping it focused and centered at high power, and ants kept going at her bare feet (she was standing in the flower gardenæ‚  was huddled in an awkward spot trying to avoid the neighor lights), so she went inside to bed shortly afterwards.

I spent some more time admiring the Ring, then just lay back in a lawn chair and naked-eyed it for awhile. It's a grand universe.

Time 22:30-23:40 EDT
Clouds: clear
Transparency: above average
Seeing: poor
Darkness: complete
Pollution: typical Philly skyglow, plus lots from neighbors until last half hour

Long Time, No Blog


Long Time, No Blog

Well, no astronomy blogging. My "main" blog has been quite busy.

The weather hasn't been very cooperative with my schedule, lately. I've popped out with binocs a few times, but the big scope hasn't been hauled out in awhile. Hopefully this week.

More Time? Maybe


More Time? Maybe.

I've retired from being a big deal web executive. Maybe now I'll get a little more scope time.

Blind Spots


Blind Spots

I suppose you've heard by now that we had a large asteroid pass by fairly close to us (about 1.5x the distance between us and the Moon) with no warning. It wasn't even spotted until four days after it passed us. Press coverage was the usual silliness.

What interests me about this is the whole idea of an astronomical blind-spot. One of the problems a science fiction writer faces these days is that most readers understand that it'd be very hard for anything large to approach Earth from outside the solar system without us seeing it days, weeks or months ahead of time. One has to either have amazing accelleration capabilities, some kind of warp or hyperspace capability that can operate close to a massive object, a cloaking capability, blah blah blah.

It's all been done, and it's not a trouble to just repeat an old formula, but what if you want to write something that doesn't depend on any of those things?

Well, this asteroid pass provides another tool for the sci-fi writer's toolbox. It may even have been employed in the past, but I don't recall reading it anywhere. A large object, entering our system on the far side of the sun, and approaching the Earth from the direction of the sun, should be able to get right up to us without being seen. This is what the asteroid did.

This is nothing to build a story around, but it's a nice scientifically real trick to throw in during the course of an interplanetary war, for instance.

Not Much Astronomy


Yeah, not much astronomy going on for me these days.

The new baby is the main culprit. (I'm not complaining! She is an immense source of joy and peace for me.) Those very few times I've almost hauled the scope out these last weeks, the weather just wasn't there. Over the next month or two, though, things in my life and in my schedule will shift a bit here and there, and I look forward to soon getting at least a little time at the eyepiece. I am especially looking forward to taking my 4-year-old out under the stars again; he still occasionally talks about our early morning leonid party we had in November, and I certainly want to maintain support for his interest in looking at the sky.

IT'S A GIRL!


IT'S A GIRL!

My new daughter and my wife are both doing fine. The baby was born some time after 4:30p today - after we woke up to go to the hospital at 4.30a. 8lbs. 5 oz. Good ap-garr (or whatever) scores. Cute kid. More noseless than usual.

You know, it never gets old.

This Astronomy Log Is Going to Stay Here for a Little Longer


I've successfully moved my other blog over to mac.thefraziers.org. This astronomy log is going to stay here for a little longer, though. Not much happening, right now. Things are too cold on the rare nights that the sky is clear.

The Move to the New Host


Well, I screwed up part of the move to the new host. Over at http://thefraziers.blogspot.com/ there should be a message pointing people over to http://mac.thefraziers.org/tempblog/. There isn't. And there is no non-cumbersome way for me to fix that, now. So, I'm hoping to catch a few people who followed a link from there to here with this message.

In not much more time, this blog, too, will be moving. Most likely over to stars.thefraziers.org/ylog/. We'll see, though.

A More Permanent Home for this Blog


Well, one of the things that has been delaying me is that my free time has been given to setting up a more permanent home for this blog (as well as for some other web experiments of mine). The move is just about complete. I'll post the new URL when all is ready.

Much Better Views of Messiers 35-38


Much better views of Messiers 35-38.

Wasn't sure the clouds would clear, tonight, but sure enough at 1am they did. Spent from 1 to 2am at the scope out back. Gave those four clusters I've been hunting each a real look this time. Finding the Auriga Messiers (M38, M36 and M37) was much easier, this time, with clear skies, proper attire, etc.

I liked M35, but I have to say I wasn't deeply impressed with it. Failed to spot the orange star.

Spent a little bit of time hunting down the oft-ignored emission nebula in Orion, M78. Thought I had it for a moment, but it was a false alarm. Clouds started to come in and I was getting cold (and it's getting late!), so I packed it in after only a few minutes in Orion.

It's interesting, but after spending an hour looking at open clusters, it's kinda hard to mentally adjust your eye to spot faint nebulae.

At the end of the night, while packing up, I got a surprise visitor: one of the neighbors' cats was standing in my living room, wondering where the food was meant to be. It must have got in during the brief time the door was open while I carried my Dob's base into the basement. (I keep the base down there, as it's a bit of a heft to carry around, and the basement stairs are right off of the entrance to the kitchen from the outside.)

Next on my list: M78, a revisit of M42 and M43, and then perhaps a trip to Monoceros, Canis Major, or maybe one of the other neighbors. Weather forecast doesn't look good for the coming week, but we'll see.

Transparency Forecast Graph


Check out the fun transparency forcast graph at the top of this page. It's a doohickey put together by the very helpful Atilla Danko using some great data and images from the Canadian Meteorological Centre.

How's it work? Well, there are more details elsewhere, but the short of it is you look at the top row of boxes for an hour-by-hour view of cloud cover and the bottom row for overall transparency. The one on this page is keyed to the NE Philly Airport. That's not quite where I'm observing from, but it's close enough, I suppose. Note that it does not take into account transparency issues due to light pollution, and the like; it's only a quick snapshot forecast of moisture levels. The red lines mark off days (divisions between midnight and 1a), and the forecasts generally look forward only a day or two.

Ugly


Yes, I know this page has gotten ugly. I'm committing the cardinal sin of fiddling with the live version.

Saw Messiers 35, 36, 37, and 38


My fingers are numb so I'll make this quick, and maybe edit it tomorrow.

Saw Messiers 35, 36, 37, and 38, tonight. Instrument was a pair of 7x50 binocs frozen to shaking hands. Transparency was really good, tonight, but the temperature is crazy cold. No way I'm hauling my scope out tonight, especially as late as 11pm. Besides, Auriga is directly overhead, and that's a real pain with a dob mount. If it were warmer, I'd be there, though. Great transparency, like I said.

They were all blobs, as far as I could see, but I wasn't really out there that long, and holding binocs steady when they're pointing straight up, the temperature is freezing, and you're not sitting down and not wearing gloves...well, it's just not that likely. I could've dressed better, put on some gloves, and all that, but I really only popped out on a whim to catch a quick glimpse before going to bed.

Also saw the double cluster...very briefly.

Anyway, I'm amazed at my confusion the first time I went hunting for the three Auriga Messiers; then again, I was trying to hunt them through pretty thick haze and outright clouds at times, so I guess I shouldn't be too surprised.

Weather forcasts for the next few days are not promising.

Messiers in Auriga


Went hunting for Messiers in Auriga tonight. It was not a very clear night, with thin haze throughout, occasionally interrupted by streaks of thicker cloud. Still, M38, 36 and 37 are open clusters, not fuzzies, so I thought I'd give it a shot.

Found M38 without too much difficulty. Looks more like a star than the letter 'pi', to me.

I then fumbled around for some time looking for M36. Eventually I found a compact open cluster about where I expected to find M36, but on reflection, now, I may have had my bearings crossed. Star-hopping in tonight's sky was very difficult, and Auriga is so densely packed that I may have overshot M36 and instead seen M37.

Two things cause my suspician (well, three things):

1.) The diameter of the mystery cluster seemed larger than I expected, and looked a lot closer to the diameter of M38 than I imagined. (Both M38 and the "supposed M36" fit nicely in the field of my 10mm Plossl.) M36 should be a lot smaller than the other two, if I recall correctly.

2.) I checked some photos of the three clusters on line, and what I saw looked a tiny bit more like M37 than M36. Of course, I'm not positive about this.

3.) After thinking I had found M38 and M36, I went looking for M37, supposedly the "showpiece" cluster in Auriga, the "Winter Salt and Pepper". Now, my feet were going numb from cold, and the cloud cover was getting worse, and I was thinking about when I had to get up the next morning (I started observations around 10.30pm local time, and only just ended a little after 1 this morning), so my patience wasn't what it might be. I eventually gave up. It seemed strange, still, that I had found the other two, and yet had no luck finding the "showpiece" one. Yeah, I didn't give it the same effort, and I was tired (am tired), but I did kinda expect it to be a bit easier to find.

Anyway, I'm not counting this as "seen". So for tonight, I can only really claim to have seen and identified M38.

Since this blog is not as old as my hobby (which only got serious last August), I'll do a quick Messier recap:

* Andromeda Galaxy through 7x50 binocs, and through a 6" f/8 dob (25mm and 10mm plossls).
* Pleides naked eye, 7x50 binocs, and through the dob w/ the 32mm plossl (both with and without LP filter, looking for the nebulosity and eventually seeing it).
* Orion Nebula through the binocs and through the dob (32mm, 25mm, 10mm, plus all with and without the 2x barlow, both with and without broadband filter).
* Ring Nebula through the dob (32mm, 25mm, both with the 2x barlow, plus the 10mm, all with and without the filter).
* Crab Nebula (just barely!) using the dob (32mm, 25mm, both with the filter).
* M38 using the dob (32mm, 25mm, 10mm).

Of course, I've seen a bunch of other things, many before I knew what I was looking at. Especially liked the double cluster, Jupiter (best when a moon's shadow crossed it), Saturn and the Moon.

I'm in no real rush, and I don't get to go out and look up that often, plus the light-pollution here is terrible. I'd kinda like to ID about a dozen Messiers between now and March. During those months I'm wandering about Taurus, Auriga, Gemini, Orion, Canis Major, Puppis, Monoceros, and Lepus. Oh, and Lyra, I suppose. I caught the Ring Nebula, there on a very rare, clear evening in which the kids had finished dinner very early and had an hour before bedtime or so. I'd like another such chance to go after the other Messier in that constellation, but we'll see.

Time for bed.

Here It Is


Yep, here it is: a place to stick my astronomical observations, musings, etc., where they won't clutter up, wash out, or otherwise overrun my more random and general-purpose ramblings over at my "other" blog.
