Except that I never get up until well past dawn I would like to do that Maybe after David retires and we go to bed at a reasonable hour like normal people. Though we have many months of the year with not a single cloud in the sky so it would be seasonal if we do get them at all.
The first thing does not have to be a problem - you can see them in the evening as well. Where you live, halos are for sure seasonal. Do you know this weather when the condensation trails remain in the sky much longer than usual? That's the typical weather for a halo - not really cloudy in a classical sense, but like a thin silk veil in the high atmosphere. Anyway, I wish you luck for your "hunt"!
Ich verstehen, dankesehr. I can only remember seeing the trails from planes about twice ever. David is outside for many hours a day and he says those times are really, really rare. It looks like a job for when I go on holidays LOL
