There is Fri, 20 Nov 2009 13:40:09 GMT gustavo http://tech.groups.yahoo.com/group/comets-ml/message/16142 http://tech.groups.yahoo.com/group/comets-ml/message/16142 I will take more pics today, this is the result of my shots yesterday evening. http://astrosurf.com/nazaret/images/cometas/107/107-091119-J47.jpg shows Fri, 20 Nov 2009 10:55:10 GMT gustavo http://tech.groups.yahoo.com/group/comets-ml/message/16141 http://tech.groups.yahoo.com/group/comets-ml/message/16141 Hello group.! I did an observation with the 12" and st-8 yesterday afternoon. the shoots was very low, 14º over the horizon, but the night was very good and Fri, 20 Nov 2009 10:31:34 GMT Maik Meyer http://tech.groups.yahoo.com/group/comets-ml/message/16140 http://tech.groups.yahoo.com/group/comets-ml/message/16140 Hi all, ... this is typical for comets close to earth: they exhibit a (very) large and faint outer coma which is much more easily visible visually with SMALL Fri, 20 Nov 2009 10:27:15 GMT Roman Kostenko http://tech.groups.yahoo.com/group/comets-ml/message/16139 http://tech.groups.yahoo.com/group/comets-ml/message/16139 I have imaged this comet on Nov. 17.52 UT remotely from D25 Tzec Maun Observatory. I also had some doubt about its magnitude - certainly brighter than 17.6m, Thu, 19 Nov 2009 14:35:16 GMT Juan José González Suárez http://tech.groups.yahoo.com/group/comets-ml/message/16138 http://tech.groups.yahoo.com/group/comets-ml/message/16138 Rob, Sincere thanks for your image and kind words. 169P is now approaching perihelion ( T 2009 Nov. 30, q=0.608 AU ), developing a wide faint coma. A very dark Thu, 19 Nov 2009 13:17:22 GMT francois kugel http://tech.groups.yahoo.com/group/comets-ml/message/16137 http://tech.groups.yahoo.com/group/comets-ml/message/16137 I imaged it on Nov. 10.00 in remote from San Pedro de Atacama : 0169P C2009 11 10.00035 18 06 24.84 -21 36 40.3 17.0 N I10 Francois Thu, 19 Nov 2009 13:08:23 GMT terryjlovejoy http://tech.groups.yahoo.com/group/comets-ml/message/16136 http://tech.groups.yahoo.com/group/comets-ml/message/16136 Interesting. I imaged the comet's position on Nov 11.4 and nothing was visible brighter than mag 13. So this looks like a very recent development.

I managed to get a rough widefield image of the field tonight in fairly poor sky conditions (dust). 169P shows (just), but it appears to be Wed, 18 Nov 2009 22:42:08 GMT Juan José González Suárez http://tech.groups.yahoo.com/group/comets-ml/message/16134 http://tech.groups.yahoo.com/group/comets-ml/message/16134 169P/NEAT: 2009 Nov. 18.77 UT: m1=9.2, Dia.=4', DC=2/, 20 cm SCT (100x). [ Significantly brighter than expected. Elongated wide coma with faint outer region.

In that regard there is a nice calibration Mon, 16 Nov 2009 17:20:10 GMT Bob King http://tech.groups.yahoo.com/group/comets-ml/message/16132 http://tech.groups.yahoo.com/group/comets-ml/message/16132 Hi all, I first tried to spot C/2009 Q4 Boattini on October 21 in my 37cm reflector but was unable to see it.
