Asteroid 3200 Phaeton passing by

Recommended Posts

Interesting Apollo class asteroid going by in early December, possible progenitor of the Geminid meteor shower.

May reach Mag 10.7 around the 10th.

Very cool finding! Where did you find the information on this? Or did you just chance to hit on it while playing with your Stellarium? (Which can be both educational, as well as lots of fun!)

I just found Ross 128 in my copy of 'Stella.' The latest possibly habitable exo-planet and only 11.03LY. See my new posting on this.

Thanks for Phaethon!

Can't claim any credit, it's in the December issue of Sky at Night magazine, thought I'd pass it on :)

Had a quick look for it through the 10"SCT last night / this morning about 2.30am after doing some imaging, can't say as I saw it, will try to spend longer on it next time.

Phaethon gets a mention in Astronomy Now December issue as well. I’ll give it a try to track it down during its close approach.

I managed to find Phaethon tonight with my Watec camera through the Celestron C9.25. It`s motion was obvious after a minute or two.

Got a reasonable sequence of it last night will try to get it processed later, crossed the Atik 314 frame in about 30 minutes.

Look forward to seeing it!

I downloaded some charts today, hopefully if the weather improves I can combine viewing/imaging the Geminids and their source this week.

Managed to catch the little devil after a couple of false starts trying to get ahead of it to get it to cross the frame, bit tricky with 10" SCT and Atik314, about 35 minutes of images.

Great catch.  I managed to get it a couple of nights ago.  I use Cartes Du Ceil for mount control and it is easy to update the asteroid/comet database from MPC and so use CdC for goto.  Like you it took a couple of shots and blinking between frames to spot it.  I then did a couple of longer exposures to show the travel.

Good fun getting something travelling at over 30km/s!

Thanks Helen, spent a while nudging the scope to try to catch it coming into frame, should have used DSLR but already had the Atik setup.

Yes, a larger fov would have made life easier, but using something already set up and working minimises the risk!  I decided to set up my Atik460 for live viewing using the Infinity software, but that required new drivers, so I duly installed those.  The result was the Atik 460 worked nicely with the infinity software.... but stopped working nicely with Maxim :rolleyes2: So the planned sequence of starting with Maxim to plate solve to be sure of location and then moving to live view was scuppered.  But did get there in the end :happy11:

Excellently captured, I am guessing I am not going to catch it on a fixed tripod with my Nifty Fifty lens!

I saw it last night (15 Dec).Found it easily with the GoTo of my C8SE. Observed it between around 23.05-23.35 pm.  The predicted position changed from around 01 27' 00", +35 52' 50"  to 01 25' 25", + 35 41' 44" during this time, moving nearly halfway across the FOV of a 25mm eyepiece. Around 23.35 pm when it passed near some stars the motion was evident within a minute or two.  Asides from satellites, I have never seen anything in the night sky move so fast.
