Update on Comet 168P/Hergenrother

Our team performed follow-up observations of comet 168P/Hergenrother on 2012, Oct. 22.4, remotely through the 2m, f/10 Ritchey-Chretien + CCD of Faulkes Telescope North (Haleakala) under good seeing conditions, and a scale of 0.3"/px. Comet 168P has recently undergone an outburst with its magnitude increasing from ~14-15 to magnituide ~9.5. For more info about the recent outburst of this comet, see our previous post here.

Recent observations posted on comet-images ml were showing a "cloud" of material trailing the nucleus in the anti-solar direction. In our image (stacking of 9 x 30-second exposures) is visible an unresolved and diffuse trail about 6" long and 3" wide in PA145. Click on the image for a bigger version.
