Dear colleagues, I updated the light curves of two remarkable periodic comets, 141P and 9P. Michael Jager succeeded to observe 141P as around 12.0 mag. It is ...
... mag. ... bit ... Dear Seiichi, thanks for your update. I'm waiting with interest the first visual estimations of 9P/Tempel: up to now the photometry on...
... Hola J.J. so finally you get it: congratulations! I have seen that also another Spanish amateur has seen comet 9P/Tempel almost simultaneously with you,...

Hello all, Did anyone else notice the particularly strong non-gravitational parameters published in the latest MPEC for comet 2004 T4 LINEAR? ...
... Hi Michael and all, Nakano published an orbit several days ago [NK 1169], also with pretty large non-gravitational parameters, using a different model...
... Hello Michael! The non-gravitational accelerations (a_i) are expressed as : a_i = A_i * g(r) * e_i where A_i are the parameters A1,A2,A3 and e_i are unit...
Would anyone care to estimate, very roughly speaking, how much time it would take a comet to travel from the Oort cloud to the inner solar system? Thanks. Bill...
Dear colleagues, 21P/Giacobini-Zinner is already in the morning sky, and it must be already bright as 15 mag. However, nobody succeeded to observe it since...
Dear colleagues, The following comets are waiting for the first observation now. 141P/Machholz 2 was observed by Michael Jager on Feb. 27 at 12.0 mag, but not...
Dear colleagues, My "Weekly Information about Bright Comets" page: http://www.aerith.net/comet/weekly/current.html was renewed. I had written only "one-line"...
The time of that trip, of course, would depend on where in the outer (classical) Oort cloud the comet began its inward plunge. If your looking for an average,...
Seiichi, Thank you for your weekly information on bright comets. It is one of the few places where one can find good information on all current and near term...

Dear colleagues, 105P was observed at 18.8 last night. 21P was 16.1m. This is unfiltered assessments. I want to inform you that my further assessment (MPC...
Dear Filip, ... sure, you can upload images to the images or files section of the group at http://groups.yahoo.com/group/comets-ml Attachment are not allowed. ...
Dear colleagues, The actual position of 141P/Machholz 2 is off from the predicted position. Based on the observations by Michael Jager, the perihelion date of ...
Dear Seiichi and all, It looks like to me that Michael observed fragment 'A', not 'D'. MPC 45656 gives the orbital elements of 'D', but the T you mentioned is...

... Dear Seiichi, I find that Michael Jaeger's images are slightly better fitted with T = 2005-02-28.246 UT. This gives a current position that differs from...
Hi all, ... I have measured Michaels first image with Astrometrica and sent it to the CBAT. The resulting correction in perihelion time was +0.5 day, exaclty...
I have a Galileo 800mm X 80mm reflector telescope with 16mm and 20mm eyepieces, it came with Galileo Trilogy software planetarium ver 1.8. I dont know what...
Dear Akimasa and Reinder, Thank you for your information. ... Thank you. Well, I could confirm that I searched the correct position visually on Mar. 8,...
Hi all, returning from a business travel from Berlin I found in my mailbox (snail mail) a preprint of a paper by Z. Sekanina and P. W. Chodas titled "Origin of...
Dear Filip, ... Thank you. MPECs were issued after your post. Today I updated the light curves of them, and updated the information in my web pages. Best...

I wanted to print out comparison charts for comets, available on http://www.shopplaza.nl/astro/. I opened up the image file successfully and am able to read it...
In usual conditions at height of 170m above sea level on 10 March the comet 141P/Machholz has not been found in 30-cm Newton at a limit on stars 12m. Zodiac...
