Hello Jakub
comet 2P/Encke is clearly a gas rich (or dust poor) comet, this is confirmed by a number of CCD filtered data from different observers. About...
Dear Jakub Cerny, ... Sorry for confusion. The magnitude of comets in my ASAS-3 images page mean predicted magnitude. They are not the measured magnitude from...
Another few thoughts about multicolor CCD cometary photometry: 1) you should consider the error budget of the nmeasurements: for a comet around magnitude 11,...
Thank you Giovanni, now I have clear in this thing! BTW. I hope some whole BVRI photometry of T7 will come early, and maybe if David try to make BVRI on C/2001...
... sounds a little exaggerated. In >the past, I measured pretty dusty comets, like C/2002 F1 (Utsunomiya): on April 2002 it showed a very >nice parabolic ...
Hi list, I have uploaded new images from 6 comets to my homepage. Regards, Stefan Beck http://www.cometchaser.de "Astrophotography with small telescopes" ...
Dear colleagues, The Session of Cometas /REA Brasil publishes starting from this month the Bulletin Electronic Costeira1 - Comets in the format PDF. The...
Hi Stefan, I find your very beautiful images, compliment! I inform everybody that I have adjourned the page of the site comets Italian (http://comete.uai.it/)...
Dear colleagues, 2P/Encke is now bright. Some visual observers reported the large coma about 10 arcmin. However, some CCD observers reported it looks stellar ...
Hi Hermanus, I did two visual observations of Q4 tonight seperated by a few hours. It's looking nice and 'bright'... C/2001 Q4 (NEAT) 2003 November 02.37 UT:...
The elongated aspect of the coma and because the comet is now about the descending node suggest me that we could expect an inminent nucleus disruption. Best...
Greetings comet friends I have found an interesting southern hemisphere site with many nice pictures. The observer is named mmatti but I can not been able to...
Eric, it is Michael Mattiazzo. I think you also find him in this group. Quote on his website: "Send comments to Michael Mattiazzo : mmatti at yp-connect.net" ...
Hi John, thanks for the observations of 2001 Q4 of last night. I've added them to my analysis of comet 2001 Q4. At present the brightnees evolution of 2001 Q4...
Dears friends, Recent magnitudes estimates for C/2001Q4 (from Brazilian observers) are available at http://costeira1.astrodatabase.net/cometa/observ01q4.htm...
... results there are. Hello Rolando, as you know, when performing CCD photometry there are a number of factors that could influence the data. Actually I...
Hello Hermanus, I found few additional estimates on Brazilian comet section (link - http://costeira1.astrodatabase.net/cometa/observ01q4.htm i found it in REA...
Hi all, with the recent solar activity, storms, and aurora I wondered if they might have stirred up a bit of 'life' on Schwassmann-Wachmann 1. I tried to see...
Hi Giovanni, is right on the conversion between Tycho and Johnson, to make the measures me I have used the program of the Afrho, I hope that who has planned it...
Hi Jakub, I have noticed in the last few months that predicting the brightness evolution of 2001 Q4 is very tricky. First, there are not so many observation of...
Hermanus, This is all of my CCD integrated magnitude data for 2001 Q4. It represents the total USNO R magnitude for the entire coma and is about +/- 0.3 mags....
Terry, ... nevermind, it is of general interest and response to a special question. By the way, I can confirm the low photometric parameters of C/2001 Q4 and...
... who has ... No, in the Afrho software you are using, you should type by yourself the appropriate *Johnson* magnitudes. For those interested, I inserted in...
Hello all, The website address is http://www.yp-connect.net/~mmatti/ Find my latest image of C/2003 T3 Tabur taken on October 22nd. 7x20 sec exposures. The...
Hello, back from holidays in Bavaria I took some images with EOS 10D of Encke and HT50. Especially the M31 passby at 25th October. If you like check out at ...
Dear Jakub, it is the first time I write in this mailing list. I am happy to see that there is interest in multicolor photometry and that Giovanni has already...
Hi Hermanus, I can totaly agree with you. For my result (photometric parameters near n=3 and H0=5) I use for computing it only observations after solar...
Hello Maik and Terry, first, thank you Terry for your CCD data, it says a many about comet (especialy if it's made by one observer with same instrumets :-)....
