Dear comet friends, Although for a moment this comet's tail seemed to vanish, tonight's images seem to show it is alive and well, mag is 10.70 (10" box)...
Same night, Only reprocessed the tail structure and co-added all usuable images. Measured a 22' long tail (it is clearly lost away from the CCD chip), and the...
Dear colleagues, Two comets, 126P/IRAS and C/2009 P1 ( Garradd ), are appearing in the morning sky at 15 mag. These comets have not been observed for a long ...
Hello Seiichi and all, I observed 126P/IRAS on June 03. 0126P C2010 06 03.11477 02 35 08.28 +38 58 38.5 16.2 N A77 0126P C2010 06...

... Thanks for the heads up. Images taken thru thin cloud a few minutes ago at E12 show it at mag 15.6T. It is strongly condensed with a coma 0'.3 and tail of...
Hello ! There is a very hot weather these days in Romania and the sky conditions are poor even if the sky is clear. Here are my last observations on C/2009 R1:...
Artyom C/2009 R1 McNaught has been playing around naked eye limits for at least the last four or five days but there was no doubt this morning's that...
Hello all! I want to make up the database of bright fuzzy objects for usage as a source of magnitudes for naked-eye comet observing. For this purpose, I ask...
Artyom, While such magnitude listings already do exist (Max Beyer and I did one perhaps 30 years ago), be advised that such a compilation of magnitudes for ...
John and all! There are many DeepSky objects, they are different. The comets are different too. => It is possible to select, to choose suitable. P.S. Sent me,...
Dear Artyom, m1 photometry using deep sky object will not be considered by the ICQ. The accuracy it’s much less than the usage of stars. One reason is that ...
Hello Comet Lovers, I was able to sandwich getting a spectrum between getting over my trees and beating the sunrise on morning of 6/20. The spectrum appears...
Hi all , Update the light visual curve of comet C/2009 K5 McNaught , based in 79 magnitudes visuals from ICQ and lists of yahoogroups.com observadorescometas...
Hi all, I have updated my analysis of the currently brighter comets. You can find it at the URL http://kometen.fg-vds.de/aktause.htm Regards, Andreas...
Hello all, I have done some fast analysis of brightness evolution of comet McNaught. For me it seems, that growing of nucleus activity almost halted at 1.17 AU...
Dear Jakub, I checked you values with the help of Seiichi Yoshida's Comet.exe. Your parameters do'nt fit at all. I calculated m1 = 6.66 mag + 5 log(D) + 9.13...
Hello Uwe, my calculations leads from datas which are available to me atm (ICQ recent mags, Comet Obs group and my own observations). I added formulas, which u...
I can confirm that this comet has been losing in brightness relative to the MPC ephemeris V magnitude. Most notably tonight (June 25.9), the ion tail is a lot...
I'd like to share my analysis of C/2009 R1 (McNaught)'s lightcurve. You can find it at (transientsky.wordpress.com). I agree with Jacob and Richard that R1 has...
