Re: SWAN comet hunting
I recommend using the _rfa versions of the images ¨C especially when looking close to the solar occulting area, e.g. swan_ARecl_sm_20241205_0002_rfa.gif. When you do so, you¡¯ll see more unblocked

Re: 2015CD60
Hi Roberto, all, Nice job Roberto! I can confirm that this object is exhibiting cometary behavior. On images I took yesterday with LCO-Tenerife (0.35-m Cassegrain) it is clearly showing a small

I _think_ the advice given here applies (you may need to check with the CBAT folks) : https://www.minorplanetcenter.net/iau/info/NonEnglish.html So for Miko?aj, send Miko\laj. (Ideally, they'd use

Re: SWAN comet hunting
My advice is not to send anything to CBAT that only appears in 3 SWAN images; I would consider 4 images a bare minimum. Personally, I don¡¯t see any moving objects that disappear behind the black

Re: SWAN comet hunting
I think I have found something. The sky wasn't searched in that region and the object is seen in 2-3 images, but it then disappears behind this black thingy covering? Sun on the left.

Re: 2015CD60
Hi Miko?aj, In this case, 2015 CD60 would be formally considered a Jupiter-family comet from a dynamical standpoint (commonly used in the active asteroids literature)--the distinction being that 2015

Re: SWAN comet hunting
Good night, Mikolaj! Close but not exactly. On 4/12 333P was 7-8 degrees above your mark. On 3/12 this comet was in X-Y position at 335-196 (0,0 - upper left) - in the attached SWAN image it is easily

Tail presence doesn't necessarily mean it is a comet. There are asteroids that have their tails. Nice photo :P --Miko?aj Kaszczyk

Object 2015 CD60 is definitely a comet. From images taken on December 2nd (unfortunately analyzed only today) I noticed that the object 2015CD60 (object that I follow together with others to see if it

As I know, SOHO mission will be certainly working until end of 2025, but it might be extended ¨C it goes very well ¨C but the time will tell. Thank you all for help!

Re: P223bel = COMET 213P-B/VAN NESS
Hi Sam, Piero, Adrien, all, I¡¯m inclined to suspect that this comet has indeed undergone an outburst, or at least some kind of upsurge in brightness, during the fairly recent past, given that it is

Re: P223bel = COMET 213P-B/VAN NESS
Hi Piero and Adrien, It has been officially identified by the MPC as 213P... I'm not 100% sure that identification is correct due to the magnitude difference, but this comet is prone to outbursts so

Re: P223bel = COMET 213P-B/VAN NESS
Hi Adrien, As far as I know, in addition to the main one, we only have the B component. The problem to be clarified is whether the observations of PCCP - P223bel - are to be referred to 213P or

Re: P223bel = COMET 213P-B/VAN NESS
Hi Piero, Great! Sorry for my na?ve question, I don't know the whole story behind 213P. I see in JPL's SBDB that there is 213P and 213P-B -- i.e. the latter would be a piece of the former, but I

P223bel = COMET 213P-B/VAN NESS
Hi all, Last night G. Ventre at Sormano2 (L06) obtained images of P223bel now in PCCP. The calculation of its orbit indicates to me the recovery of the comet 213P-B/VAN NESS. Piero Sicoli

Re: 333P 40' from Mizar
David, it was cloudy last night here in the desert and with 333P moving almost 10'/hour across our skies I wonder if Mizar would have still been in my comet FOV by the time it rose in the desert. 333P
