Re: unusually bright asteroid/update

Oh dear, guess what bug has just resurfaced?

I have just been looking at some routine displays and there was an asteroid showing mag 2.3! 2010DK71 has appeared despite my using (1) the latest MPCorb (16 May) and the latest Guide version.

Some bugs just refuse to leave.
