Location: Ceccano, Italy

Images taken on the morning of March 12. The sky was very clear, and the comet tails were clearly naked-eye visible. The first picture has been taken using a 180mm f/5.6 lens, and shows a two-frame mosaic. The field of view along the diagonal is about 3.4 degree. Each frame 2 min exposure. The second picture has been taken using a 150 mm f/5 reflector telescope and shows a four-frame mosaic. The field of view is about 1.1 x 0.7 degrees. All the images have been log-scaled using a software done by me. CCD SBIG ST-7 Location: Ceccano (FR) Italy, 231 meters above sea level.
