They're also visible just after 1st and 3rd quarters. After a day or so I
find that they become invisible till the full moon when they show up as
white dots, as you say. The seeing has to be very good to spot all four (or
five for the larger scopes) but I find I can spot a couple in even average
seeing if the time is right.

I find claims of perpetual bad seeing in the Midwest somewhat puzzling as in
the summer the jet stream isn't that active over the upper US latitudes.
Even here in the Pacific Northwest, it calms down and seeing improves
greatly in the summer months. However I do find that on clear, warm days,
seeing after nightfall isn't immediately great. You have to wait till early
morning for the air to give up its heat and settle down.

Tanveer.
