Comet Linear 2002 T7 in Tri is a nice object tonight with short
eastward pointing tail. Spectrum taken previous evening shows essentially reflected sunlight and no obvious emission lines. Has any obvious cyan colour been recorded? Pic at http://home.freeuk.com/m.gavin/encke.htm Maurice Gavin@WPO-UK |

Hi Maurice, There have been a few recent colour images posted on the Yahoo group comets-ml, but no real colour showing in the tail currently. Unlike 2P Encke which showed cyan very nicely Robin |
