Monday 31 August: G1
A G1 event happens almost never during solar minimum but almost all the time otherwise. There have been 166 spotless days this year, and today is a spotless day. Very often sizable spots accompany G, R and S alerts.
Is Solar Cycle 25 awakening?...

Tony Phillips recounts NOAA's declaration that a high-speed stream of solar wind may hit the Earth's magnetic field in a couple of days. We'll know soon if there are any effects.

There was a dire prediction yesterday that the Earth would be staring down a Level 3 Geomagnetic Storm; happily the confrontation did not come to pass. An interplanetary shock from a coronal mass ejection was detected last night at 7:32pm, but there was not the necessary potential for a G3.
