E. Frappa took this image in broad daylight on January 13.56. The hand of Maylis Lavayssière is about 2.5 meters in front of the camera and is blocking the sun. Frappa estimated the comet's magnitude as -6±1 magnitude and said it was easily visible to the naked eye. The photograph was taken with a Canon 20D and a 70-200mm set at 131mm. The camera was set at ISO 100 and the exposure was 1/250 of a second at f/11.

B. Pitcher is an airline pilot. On January 13, he was flying from Amsterdam to Cancun. Somewhere over Bermuda he saw the comet out the cockpit window (January 13.96) and took photographs with his Sony Cybershot DSC W70 digital camera. The plane was then flying at 33,000 feet. The comet was barely visible in the images sent to the webmaster, but I took two images and overlaid them in PhotoShop to bring the comet out a little more.

In this image from SOHO taken on January 14.50, the sun is at the center of the image and blocked by an occulting disk, while the comet is located near the lower left of the field with the tail streaming upwards and to the left. The brightness of the comet's head is strongly saturating the pixels of the CCD chip which causes the horizontal spikes. For comparison, Mercury is located just below and to the right of the comet's head.

In this image from SOHO taken on January 15.87, the sun is at the center of the image and blocked by an occulting disk, while the comet is located near the lower left of the field with the tail streaming upwards and to the left. The brightness of the comet's head is strongly saturating the pixels of the CCD chip which causes the horizontal spikes. For comparison, Mercury is located to the left of the sun, almost directly above the comet's head.
