to seasoned astronomers, how long to wait for clear weather?

Remember many weeks of continuous cloudy weather (that was pure fustration) before we saw that really great comet Hyakutake in 1996.

Yep, that's true, I remember that during the first week of it's great appearance it was cloudy

Keith..

Thats comparing a week or 2 of clouds to 4 months of storms and rain,
some comparison

Yep,

Here we had:

Sept 06 = 2
Oct 06 = 2
Nov 06 = 0
Dec 06 = 1
Jan 06 = 1

Even at that the last two were through cloud gaps.

Mind you, there was plenty of solar observing possible in Sept & Oct.

Much more of this and even the youngsters amongst us will be weatherbeaten.
