Example observations of comets.

"Pi of the sky" automatic trigger has discovered the comet C/2007 W1 Boattini passing. It was found by algorithm dedicated to detection of the nova stars.

Below there are some pictures taken on 6^th of May 2008 (day of discovery by our cameras), 100x100 arcmin cut (click at the picture to enlarge):

And here there is a path of the comet through skies (100x100 arc minutes, click at the picture to enlarge):

Below there is our lightcurve (click at the picture to enlarge):

In the table there are coordinates and brightness for each point:
