A day with clouds and sun. More clearings towards evening.
Still clouds: thick, thin and very thin with nice clearings in between.
Aligned the mount on Vega and noticed in the predictions that
2 minutes later 43145 would pass just below Vega.
Althoug the predicted magnitude was 8.4 the sat showed up nicely
in the images.
