Looks like the Dragon will be about 3rd magnitude and a minute or two behind the ISS.

With some luck, we might be able to see this.  I saw the Shuttle chasing the ISS and it was memorable!  There are two possibilities tonight but you’ll need a good horizon NW to NE.  Don’t know how bright the Dragon will be so keep the binos handy – The Shuttle was easily visible naked-eye.  I think I might have a better chance than the VB area because for once Soggy Ole Maryland has a somewhat better cloud forecast and the ISS will be higher in the sky here.

Re: There's a Dragon Chasing the ISS- engine bell question

True – Many large rocket engines are made, at least in part, of coils of thin-wall tubing, fused together, through which the fuel and/or oxidizer are circulated before burning.  That both cools the engine and pre-heats the fuel.  Amazing technology – The flame of combustion separated from, often, cryogenic liquids by just a few thousandths of an inch of very expensive metal.  The F1 engines used liquid oxygen and kerosene.

I watched the launch video. Was the second stage engine bell glowing?

I've never seen that before. Didn't rockets designed like the F-1 engines on Saturn V, et al- a la Von Braun have cooling built into the bell?

BBAA Membership without AL

Lawrence Taylor
 

Stargazers,

Mark is joining the BBAA and is a lifetime member of the Astronomical League (AL). Are there accommodations with AL that will permit BBAA / Mark not to be double charged for his membership? There is also the issue that he will continue to submit directly to the AL and not being confused with a redundant or new AL member account.

Please advise.

Clear Dark Skies,
Bird

Re: Comet C/2012 K1 PANSTARRS

I was able to view (just barely) PANSTARRS w/ my 8" scope from Yorktown, even with the Full Moon. Thanks for the suggestion. Hope to check it out again along with Jacques next new moon. Puppis is too low at my house and it is also made more difficult to see by the air force base sky glow.

Puppis was behind a tree for me last night but no doubt both should be visible even from light-polluted skies with a moderate size telescope. C/2012 K1 PANSTARRS was easily visible from my driveway in Virginia Beach with the nearly full moon just rising. I can't wait to see them in a dark sky when the moon gets out of the way.

Re: Comet C/2012 K1 PANSTARRS

Um, Kent, the comet I mentioned was C/2014 E2 Jacques, a new one in Puppis at mag 9.8.  Sky Tools says Jacques is larger (6.3’) than C/2012 K1 PANSTARRS (2.4’ at mag 9.5), so Jacques will probably be a bit less obvious (but it’s getting brighter), however should still be easy.  In a few nights when the moon gets out of the way, both comets should be very nice at about 9 PM, but in nearly opposite azimuth directions.

This is an easy comet. It's quite easy in my 14" from Va Beach skies even with the full moon up. Look high in Bootes for the 9.8 magnitude comet. Thanks Roy Differient for alerting me to it. Kent Blackwell

Re: More lunar eclipse [1 Attachment]

Kent Blackwell
 

Ah, too bad, George. You were just a bit too late. My pictures are time posted at 02:59:56, 03:01:09 , 03:01:03 and finally 03:13:05 AM EDT. There were other clearings as well but Kent was so nervous he was fumbling around. With all the passing clouds I felt as if I was trying to view and photograph a SOLAR eclipse where every precious second counts! In the end, it was glorious. Maybe those precious moments of clear skies made it even more exciting.
