I'm going to estimate that perihelion occurs around 2021 October 17.8 UTC or 0.5-1.0 day earlier than predicted.

Kracht group comet 2021-10-17 = 342P ?

Worachate
 

Hello all,

I'm detecting a moving object in C3 that may be the return of 342P/SOHO.
   
Images: C3; 1024x1024 images.
(0,0) Upper Left.
2021-10-17
0954 641 467
1006 643 467
1018 645 467
1042 648 466
1054 650 466
1106 652 465

If it is 342P, the comet has arrived earlier than expected. It should appear in C2 in delayed data soon.

I am retracting my endorsement of this object. I am not 100% sure, and I do not want to jump to conclusions, Karl will decide who claims this comet.

Thanks for the checking, really interesting object. 


Re: Potential C2 Kreutz comet 20211015

Now that makes *perfect* sense Worachate, since I used the 10/15-17 plot to check the trajectory. I also checked more C3 images, and it looks like Masanori reported something that is real. I am willing to endorse the C3 report. If the C3 report checks out with Karl, Masanori will receive the credit for this discovery.

I think placement of the plot may be a little off. Noticed it for a long time but too lazy to fix it.

I can't see any points after 1730. Hard to distinguish the 1642-1730 points from noises.

I just realized x,y values can't be compared directly for C2 and C3. Waiting for official confirmation.

I am going to check his report again, I might have calculated incorrectly. The timing, does look right, but the location in C2, threw me off.

The comet in C3 looks real to me. I went to bed last night before checking it closely.

The timing of C2 entry also seems to get along well with it.

Anyway, this is just my opinion. You need to wait for the official confirmation.
