96- 60 A = Molniya 3-48 = 24640
94- 81 A = Molniya 1T = 23420

I have tried to observe Molniya's over the last months.
My findings are that most of the time these birds are pretty faint,
since very often I don't see anything..., meaning that they are let's
say fainter that mag 12-13.
Molniya types have 6 panels of solar arrays perpendicular to the main body
axis.
Sometimes (favourable orientation of the solar panels) they can be
fairly bright :
I saw 78- 95 A = 11057 = Molniya 3-10 at 19000 km on 98-1-26 with
flashes to magnitude +4 ! On 98-2-17 and last Saturday, I didn't saw anything...
So they can become naked eye, but 'some' luck is needed...
