I use Quicksat but do not like that the mag file is around 18 months old. I have updated a few items myself but am wondering if anyone else keeps it updated. I think it would be a good idea if someone or a few people keep it updated and then make it available for download. It is redundant for everyone to have to keep their Quicksat mag file up to date for themselves. Also what about the mag info in the new_molc.tle file? Is this comparable with mags in the Quicksat file? Would it be a good idea to some how have a centralized magnitude file that is updated regularly, that these other files like new_molc.tle, Quicksat, and SatSpy use? There still would need to be a way that each user can use some of their own mags when they generate there predictions. For example I use a mag value of 1 for some of the tumbling Iridiums so that they appear in the Quicksat prediction list, but other folks might not want them to show up in their list. It is possible to miss some of the newly launched objects unless the mag file is updated regularly. Resurs 1-4 r (NORAD #25400U 98043G) is one example of a sat that was not on my Quicksat list until I just happened to see it last year and entered it in the quicksat mag file. Now I look for it about every night that I look for sats during the summer. What about the satellite names and NORAD numbers? Could something along the same line as I mentioned above for the mags, be done with them. I understand there is a number mix up, between some of the iridium sats. If some tle files use the correct number while others use the wrong ones, there could be some resulting confusion. I have noticed that there is a discrepancy in some satellite names between the new_molc.tle file and the Quicksat.mag file. Maybe some thing is already being done that I do not know of. If such a project is pursued I'd be willing to help. I am not sure that my mag estimates are accurate enough to be used, but I may be able to keep a list updated with data from other observers.
