Kevin, I'm not sure what you are saying here but you might feel somewhat differently when you discover something yourself:) [Non-text portions of this message...
I'm saying it's confusing to have 200+ comets named LINEAR. How many has SOHO discovered now? It must be more than a 1,000 by now. If I discovered 1,000 comets...
Kevin, Oh yes I forgot ..and there are a few others too:) Please forgive me..they escaped my memory.. Yes I am all for giving credit to folks who actually...
Thanks for your insight guys! It's a shame that there's so much conjecture regarding naming of comets discovered through media other than the discoverers own. ...
Hi all. The morning Francois Kugel posted the photo of 81P/29P, I also saw the star trail to the right of 29P and dismissed it as an asteroid with a...
Dear list, sorry for this off-topic, but on the web I've found almost nothing and surely some of you can help me on this. We would like to change our CCD...
Luca, As far as I know, antiblooming works against linearity and is likely to affect the photometry of saturated targets, I don't think it may have any impact...
I agree with Juan, a wise use of the "Astrometrica" settings, regards the bright end of the magnitudes, should mitigate significantly the prpblem. Cheers, ...
Hi Giovanni, yes, of course I will set the proper settings in Astrometrica, to avoid to take stars that are under/above a certain limit. But such a CCD can be...
Hello Luca. ... IMHO it's better to constrain the dynamic range below 70%, or at least this was my esperience with a Starlight Xpress CCD I used for some time...
http://www.cfa.harvard.edu/mpec/K09/K09V10.html Only the first two nights are available via MPCOBS. I can therefore not check if the orbit is okay or if it is...
... This appears to be a routine MBA. There are only two nights of observation and the one-opposition orbit on MPEC V10 has been removed. The MB Vaisala...
Dear Rob Matson, ... Recent M.P.E.C. 2009-V04 announced that the number 228P was assigned to P/2001 YX127 = P/2009 U2 (LINEAR). A permanent number was not ...
Dear colleagues, * Two cometary-asteroids (or asteroidal comets) will be close in mid November. 2009 Nov. 15 19h UT 0.268 deg ( 16.1 arcmin) 107P/(4015)...
Dear colleagues, I heard that P/2009 U4 (McNaught) was discovered in the course of follow-up observations of C/2009 R1. P/2009 U4 had been bright before...
Hi Seiichi, ... They were reported right away. Brian Marsden and I exchanged a number of e-mails on the linkage, and ultimately came to the conclusion that the...
Hello all: 107P/Wilson-Harrington is a comet-asteroid transition object that exhibited activity on one single night in 1949, and has remained inactive since....
This is an excellent reminder, but I hesitate to agree that if we do not see activity this December that we "can declare it dead." With its past, there is...
Dear Ignacio, and all, It is good to have a timely reminder that this object is now in prime viewing position for detecting possible activity. It is nearest...
Ignacio, Thanks for alerting the comet community. I agree that during the next few weeks it is worth monitoring this asteroid (4105) for activity. My ...
I was tempted to try 107P from SSO (0.61-m, no filter) during this lunation and stack a bunch of 90-second images. On clear nights, I routinely get down to...
Dear Richard and all. ... In the few instances where asteroidal object have shown discontinuous signs of cometary activity (e.g. the so called "main belt...
Dear all, In the case of non-main belt, NEO comets like 107P (apollo) and 162P (amor) the tails have been found to be of Ionic nature (107P Yanga Fernandez et ...
Dear Giovanni, Some meteorites and presumably asteroids contain a significant proportion of hydrated minerals. Energetic particles from a solar flare would...
Dear Richard yours is a fashinating working hypothesis (as there are many others). Obviously, without a robust experimental support, I'm afraid it will remain...
Giovanni, I guess this is how science works, people come forward with options for working hypotheses and these are then compared with experimental observation....
I agree with Richard Miles that this is how science works. So it is fascinating to see so many hypothesis poping up. In this regard I would like to point out...
