This may not be a direct observation, but this really cool video from the NASA EPOXI mission spacecraft turned up in the News this morning …

The hi and medium res footage from 8 million kilometres caught two jets firing off the comet surface for a 16 hour period.

I'm excited about all this ... great captures, Liz !

Cheers

Cloudy up here last night.

Mozzie - well done!! A great feeling to find a comet after trying for a while, through dodgy weather.

Glen - wow, great report. Mag 5.5 sounds good .... I thought it was a bit fanshaped too.

Craig - lots of action there, that is amazing, thankyou.

For those who still havent found Comet Hartley, this is a Stellarium image for 1am tomorrow .
This is the data to put into Stellarium (find stellarium in your program files, open data, then ssystem, and paste at the end of the file).
Good luck.

Liz & Guys;

Here ya go …

NASA Deep Impact spacecraft visits another comet (Update)

It looks like a giant peanut !! …

or a dumbbell !!

The two ends look as though they're made from a different material than the centre band ..?.. I also would have thought that the jets would be coming from the end facing the Sun, but they do say it's "hyperative and feisty" so I guess its rotating fairly fast. I read somewhere the gas is mostly cyanide (??).

I hope you guys get good visibility for your observations.
Well spotted if you get it .. its so far away !!

Cheers and Regards

Yep .. awesome photos alright .. it might be a giant 'spud' that got away from some alien's veggie patch !

Somewhat more seriously though, is that smooth bit connecting the two halves. I thought it might have been some missing data in the image but it appears in every one of them !

Very strange looking object. I'll leave it up to the comet guys to figure that bit out.

I hope Outbackmanyep is enjoying all this ! (He's been very patient whilst waiting in anticipation for it all to unfold .. bet he's excited, also).

Cheers

This should be an FAQ.

Where are you trying to save it, and as what user, and on what operating system?

There can be two copies of ssystem.ini

One is in the program's install directory and you may not have write permission to that unless you are logged in as the administrator or "RunAs Administrator". Updating that copy is bad style in any case.

Unixish systems it will be whatever_install_dir/share/stellarium/data/ssystem.ini

Windoze it will be %programfiles%\Stellarium\data\ssys tem.ini (or whatever the x86 version of that is called on 64 bit systems)

The other may not exist but if it does is in your local settings.

Unixish systems it will be ~/.stellarium/ssystem.ini (or maybe ~/.stellarium/data/ssystem.ini since it will not run on my copy of Linux due to bad OpenGL drivers)

Windoze it will be %appdata%\Stellarium\data\ssystem.i ni

If the local file does not exist, copy the one from the program's install directory to the local settings (you might need to create the "data" directory). You can then edit to your hearts content.

This discussion applies equally to config.ini except that will have been created in your local settings as soon as you did a "Save Configuration".

Thanks for that. Done and done. It works!

Liz, I have just loaded Stellarium - where do I put this? Note I have a Mac running OSX 10.5.8.

And can anyone tell me is there any way to slightly shrink the window - it seems to default to the whole screen?

Hi Odille - so, its now on your computor, in your program files?
On the bottom line of Stellarium image are a few icons, on of which is a ....... box thing with arrows at all corners, click that, and it reduces the size. You need to move your curser over the line (under the date) to bring it up.

I can't answer the first question. Omaroo is the Mac guru. There are two locations for ssystem.ini - the one that gets installed with the program, and the one in your personal settings. You should only change the personal ones because the others are replaced every time you upgrade the program. I explained this all just the other day, but didn't include any Macisms. If you can find you personal "config.ini", and where the default "ssystem.ini" is located, the howto is a few posts earlier in this thread and should be Macifiable.

Like Liz says, if you move the mouse to the bottom edge of the screen, a horizontal menu will pop up. There is an icon that looks like a box with arrows pointing out from the four corners. If you are in "full screen mode" it will be highlighted. If you click it, it loses the highlight and switches to "windowed mode".

If you then do a config save Stellarium will start in "windowed mode" next time.

Andrew

Checked out comet Hartley last night as it rose under Orion about midnight.
Still pretty easy to find between Canis Minor and Monoceros, but it has certainly faded a bit. Back to a faint, round and nebuolous blob.

Damn straight!

I got a scaled image and its been fun trying to work out approximately how big some of the features are on the surface, i wonder what else we can extrapolate from their images!?

Comet Hartley 2 is about magnitude 7 now.
I compared it with the magnitude 6.9 star HD 57275 using out of focus 12 by 60 binoculars.
In a 12" Dob their seems to be a tail about 0.5 deg long. (maybe)
The comet is 2.3 degrees east of delta Mon.

Comet Hartley is faint in 20x80 binoculars now. It is about 3.5 degrees south of M47.
