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.

New editorial notice by MPC

The MPC has issued the new statement in MPC 69147. From now there is no point in submitting two-night discoveries, as they won’t be given priority over one-night discoveries received earlier by the MPC. As we can see, MPC gain an advantage to large sky surveys, and number of amateur discoveries will be reduced drastically.
