Dear Juan, ... I simply base it on the Tisserand parameter. This is used as a rough and simplistic discrimination between comets and asteroids. Values smaller...
... Should have showed other examples since it is not true in this context unless you take very extreme examples. Examples for odd-T are low-e comets one will...

... How about a 1000km Kreutz comet? ;) My definition of a comet: Celestial body with a cometary designation. ;) Cheers, Maik -- If they give you ruled paper,...
In an effort to standardise comet photometry, Julio Castellano has developped a tool which, based on the Astrometrica log, is able to produce accurate comet...

Dear colleagues, Latest information of comets from ASAS-3 images. http://www.aerith.net/comet/asas3/asas3.html * C/2003 H1 ( LINEAR ) It became brighter and...
Hi everyone, for a meeting of the dutch comet section I´m preparing a historical overview of the appearences of two naked eye comets simultaniously. Thus far...
I was wondering if anyone had seen this comet recently? It is a bit low for me. I saw no recent visual observations at the places I searched. Mike H....
It is perhaps worth making note here of my observation of this object made just a few minutes ago. I found it just barely detectable with 15x70 binoculars as...
John. Is there any past relationships with comets thought to be first time visitors and the comets that have come apart or disinteregrate. I probably am not...
... Hi Michael, I recently searched through my archive and found some prediscovery images of C/2003 T3. All images were reduced to yield an improved light ...
... first ... Mike, I can't say that I am aware of any definite relationship between "new" comets and a tendency for dissipation, although we happen to have...
Hi John/list, Despite the apparent slowdown in visual brightness of T7 in the last month, recent fixed aperture photometry of the inner coma (as used to ...

Dear colleagues, The following comets are not observed recently and current brightness is uncertain. 88P was observed in early January, but much fainter than...

I have noticed that Alexandre & Terry have been visually estimating the brightness of C/2001 Q4 (NEAT) about 0.3 of a magnitude brighter than my recent...
Hello Paul, You should currently be using a pair of binoculars to make estimates of NEAT rather than a telescope, as the improved contrast using binoculars...
Dear Vello, Thank you for your observations. I plotted them on the graph and updated the light curve: http://www.aerith.net/comet/catalog/2003T3/2003T3.html ...
