Comet Comments Don Machholz

Greetings Cometeers:

This is to inform you that the next issue of Comet Comments, the one you will read in the May
Prime Focus edition, will be my last one.  I am telling you this now so that all of you, especially the newsletter editor, will have time to assemble your own way of reporting comet news and positions after CC is gone.

There are several reasons why I'm retiring after 21 years of writing a monthly column.  About a year ago, I began to show symptoms of disorder which appears to be inherited; my brother has it, too.  It is not fatal and not contagious.  Medication sometimes helps; but the lack of concentration, poor coordination and fatigue now make it difficult to produce an accurate, interesting comet article in a timely manner.

There's other reasons, too.  I used to do the whole thing in three nights: research, write and distribute.  Then the internet became involved in this.  I can reach more people, but the Web page had difficulties and finally crashed (mine is now frozen on the web, I cannot change or delete it). "Fatal delivery" messages and re-sends, and writing/formatting two versions each month (electronic and paper) all add to the time the column now takes.  Moreover, with the Internet, amateurs now have easy access to nearly all the information I publish.  Finally, in the old days when amateurs found many of the comets, it was important to distribute the ephemerides information early because the comets were already bright enough to be seen in our telescopes.  Now, when LNEAR finds a faint comet, it is months before the comet will be bright enough for the readers to see it.

For the record, I got nearly all my news and orbital

elements from the Smithsonian Institution and use David Chandler's "Deep Space" program to generate the comet positions.  Before I write each issue, I visit Charles Morris' web page to see if there is anything I'm missing.  For the Comet Hunting Notes I use information from some comet hunting databases I've assembled over the years.  As for the words in the "Subject" box at the top of this letter: "1/2, or 3/4 or 5/6 or 7/9" mean that you are on these mailing lists.  I have nine mailing lists for the 100 or so copies I send out and this helps me track which ones are sent and which are delayed by "fatal errors" in the addresses.  It also helped me to change your addresses easily.

Now for those editors who wish to continue reporting about comets.  Steve Smith's "Comet Rapid Announcement Service" will be stopping soon, otherwise I would have suggested that as a resource.  Some web Pages provide tons of comet info: IAU (http://cfa-www.harvard.edu/cfa/ps/cbat.html), Charles Morris (http://encke.jpl.nasa.gov/) and one from Yoshida (aerith.net/).  Here's a index of hundred of astronomy sites: http://www.atm.dal.ca/~andromed.

Thanks for everything.  You have been a grateful audience.  I have enjoyed your newsletters you have sent to me on an exchange basis, but don't feel any further obligation from now on.  I expect to continue comet hunting, but LINEAR
et al., will limit the areas I'll cover.

Keep looking up.  Take care and the very best to you.

Don Machholz


Please accept our apologies

   The past two editions of  Prime Focus have arrived extremely late, and we apologize for the inconvenience. These delays were caused by difficulties in arranging speakers who were available on our meeting dates. President Dave Anderson tackled this problem head-on, and has secured speakers for our next four general meetings.

   The newsletters for the balance of the spring and summer should arrive at your mailing address at least two weeks before each general meeting. Thank you for your patience.
