Jupiter last night - was the jetstream wrong????

Tassie: Ok, at 8pm, the stars were the best i have ever seen them. Even down low, not a twinkle or movement to be seen. 10pm, seeing at least 6 or 7, but clouds moved in

Central Coast: eyeballing was great, but a bit messy to image

Brisbane: all three from up there are crackers, maybe not 9/10, but very good seeing???

What do people think. I have had this type of jetstream before and rated the seeing as 3 or 4 /10. And like I say, at 8pm, the naked eye view of movement was a big at 0!

It looks like I was just to the north of the edge of the stream. Still a fair bit of twinkling but not too shabby later on when looked at through a telescope (was terrible before 22:00).

Reckon that arm of jetstream over Brisbane must have drifted south as the evening wore on, our seeing came good and Sydney by Mike's account was cruddy.

cheers,

That jetstream map looks pretty tame. The effect that you can see is quite low in the scheme of things, it's around the 30 to 40 m/s mark, I think that's pretty low. I AM a complete newb so have no experience in how that map effects seeing but I have already seen orange and red on that map, which is 80 to 90 m/s, that would be bad, blue and dark blue are the low end of the scale.
