The storms passed through here around 3:30am this morning, so it was a short night. But the observing session this morning revealed again a spotless sun for spotless day 727 since solar maximum. A few small filaments and a little prom could be seen in Ha, and some plages in Cak. In 540nm the Sun is featureless today.
