C/2006 W3 (Christensen)

This is a comet discovered in 2006. Currently it about 3 astronmical units away from the sun, with no visible tail length. I did my first astrometric and photometric measurements on this picture (and I believe they are terribly wrong :) My measurement in position is off by 25 arcsecs in right ascension and nearly 3 arcminutes in declination. My photometric measurement gives a result of 9mag (should be somewhere around 8.8. However: my first comet.
 
Further info is available on www.kometeninfo.de where the info on calculated magnitude was taken from.
