Disappearance of fragment “b” of C/2007 Q3 comet

On images of C/2007 Q3 (Siding spring) comet, which taken on April 21 and 22 by FTN (Faulkes Telescope North) fragment b is not visible. Deconvolution of stacked 1 minute exposures not bring any results. Fragment b is disappeared…

Spliting of C/2007 Q3 (Siding spring) nucleus

Alison Tripp and Nick Howes succesfully observe C/2007 Q3 (Siding spring) on March 27 and April 2 at the FTN (Faulkes Telescope North , Haleakala, Hawaii). After images stacking and futher processing, fragment b is clearly visible with offset about 6.5″ from fragment a. In this case I don’t use deconvolution, because fragment b can be measured without any filters. From previous images, obtained on March 23 and 25, splitted object increased distance from parent body.

The astrometrical measurements of fragment b of C/2007 Q3, taken on Tzec Maun and Tenagra II observatories, officially published by MPC in MPEC 2010-F87 circular.

The existence of second fragment is not confirmed at this time.

Spliting of C/2007 Q3 (Siding spring) nucleus

When I seen information about spliting C/2007 Q3 nucleus, I tried to shot this event. Fragment is clearly visible on images taken on Tzec Maun and Tenagra II observatories on March 23 and 25. After processing stacked images I measure position of splited body. This object offset from parent body on 6? PA 245°. All inforamtion sended to CBAT.
