Please find enclosed a list of my recent comet observations in ICQ format.
Magnitudes are derived from large aperture photometry of CCD/DSLR images
(using green filter or green color channel) and are supposed to conform
to visual estimates of total coma magnitudes.

Remote observations were carried out using telescopes from iTelescope.net.
For image reduction and photometric analysis I used my AIRTOOLS software
(see https://github.com/ewelot/airtools).
