New Comet C/2009 P1 (GARRADD)

Cbet No. 1908 issued on 2009, August 15th announces the discovery by G. J. Garradd of a new comet: COMET C/2009 P1 (GARRADD). The discoverer describes this comet as a tailless object with an approximately circular coma 15".

We have been able to obtain follow-up observations of this object while it was posted in the NEO-CP, from mpc code E16 by mean of a 0.35-m f/6 reflector + CCD. Our image:

According to the first and very preliminary orbit, comet C/2009 P1 (Garradd) has perihelion on Aug. 10, 2011, at about 1.3 AU.

If this preliminary parabolic orbit will be confirmed, this comet may reach at least 8 magnitude in the summer of 2011.
