Good tool to predict seeing conditions

[Luis Campos]

Hi guys!

Here is a good "tool" to use to check for seeing condition on a given night, I find it very accurate and easy to interpert,  seeing is usually associated with high altitude winds (not couting on local soruces of turbulence) so here the graph shows these winds as colors and wider/thinner vectors so just chechk for the colors translation at the bottom and try! For me here in Portugal seems good for tonight but even better for tomorrow, and tomorow I'll have the GRS to play with, let's see if it goes right this time

Looks interesting. I tend to use meteoblue, which is astro-friendly and has a couple of measures of seeing.

Looks cool, I also like the arc sec. seeing prediction Let's see today how it plays here, looking for at around 8 to 10 pm
