I'd like to suggest another factor. The early passes on Wednesday UTC have been moving slowly later in time.
Last night's passes were after "my bedtime." So I was able to participate only on this morning's two passes.
Perhaps someone could look at the passes for, say, the next six months, to choose a UTC day where the passes
would be more balanced in "normal" awake times.
Another question: Are we restricted to a UTC day for the L/v operation?
