Don't think I've ever seen this before!

As good as a perfect seeing forecast, zero clouds, and a bit of dark before the moon rises. So I have the 16" out cooling

Guess MeteoBlue have never bothered to actually look at where the jetstream is ....

Isn't the Orange column in Meteoblue the speed of the Jetstream over Billericay ? Shows as 27 down to 25 m/s, 90Kph

I was being a little facetious , the speed is shown but the Netweather map show the more damning picture ...

Yes on the face of it green for seeing v the jet stream seems a bit contradictory but reading their help bit on the jet stream seems to throw some light on it. Only speeds above 35 and less than 5 correspond to bad seeing according to them.
