CommentsAn evening thunderstorm kept us closed through sunset and twilight, we were able to open for about an hour until 22:45 when opaque, but non-rainy clouds moved through. Opened again at 00:00 and were able to observe for the rest of the night, clouds cleared out. No major issues, and relatively good observing conditions after 01:00.
