Another NLC display arrived over Poltava on Jul.21 evening. As always, unexpectedly.
I wasn't observing on that night, but before going to sleep I had a look in the window and I couldn't believe my eyes - it was a NLC again. It's my first evening NLC observation!
They were low above the NW horizon, 1-2 type brightness, and type I, IIa structures. Visible from 22:10 to 22:30 EEST (possibly arrived at ~21:40)
This photo is a very low quality, because it was taken from an opened window, without a tripod, with a poor horizon and city light pollution.
But the situation looks very optimistic because the NLC activity remains high. Maybe they will arrive on the next night again.
