[BAA Comets] MPC data

[Shanklin, Jonathan D.]

I've updated https://www.ast.cam.ac.uk/~jds/cbat141.txt using the JPL elements and magnitude parameters from the comet orbit home page.  Those of you that use megastar can just copy it as comet.txt  I don't guarantee that the new elements are actually for the epoch of perihelion, which the older ones largely are.  Periodic comets are in https://www.ast.cam.ac.uk/~jds/numper.txt though this hasn't been updated as there are no new numberings.

Regards,

Jonathan Shanklin

Owen,

Yes, the lists of comets that the MPC generate for various software
tools have not been updated since May 13. The last comet in these files
is C/2019 J2 (Palomar) but it is way off track now.

This is a pain for those of us using software to control telescopes etc.

The JPL comet elements file:

https://ssd.jpl.nasa.gov/dat/ELEMENTS.COMET

is up to date, it has C/2019 N1 (ATLAS), but it doesn't include
magnitude parameters.

If this goes on much longer I'll need to generate some scripts to make
the Soft06Cmt.txt file I use in TheSky from the JPL file.

Nick.

I've not updated my Megastar format list https://www.ast.cam.ac.uk/~jds/cbat141.txt for about a month, but will do so at some point.  The information at https://www.ast.cam.ac.uk/~jds/coms19.htm will tell you if any of the new comets are interesting!
