Unfortunately this problem still exists. I downloaded the new comet data from MPC and installed in Megastar v5 yesterday the 11th February 2017. I still get the message 'unable to compute coordinates, no convergence', that is after deleting the SOHO 2010 faulty data line. I can only assume that one of the other cometary data lines is now faulty.
Does anyone know which is the line now causing the problem? Has anyone told the MPC about the problem with this data?
Any help much appreciated.
The latest update of the elements gives the following data in Cartes du Ciel:
Date: 2017-02-12 14h25m04s UT
Magnitude: 27.4 (!)
Phase: 7 deg
Distance: 5.8685 AU
Solar distance: 5.1521 AU
Mean J2000.0 RA: 19h05m42.79s
Mean J2000.0 Dec: -29d47m45.7s
If other users get similar information from their programs, then the problem is with MegaStar
and the vendor should be notified of the error (not the MPC).
