As dolanbaker said there was a spike in 2020, I think it was from late November through early December. To lazy to verify.

31 spotless days so far.

Very quiet in here.

We've had the first proper earth directed CME impact of this sunspot cycle. It was a small one and not expected to induce much of Geomagnetic Storm if one at all. If it it did reach Storm levels then perhaps it was predicted to be no more than Kp 5. However, when it hit yesterday a Geomagnetic Storm magnitude of Kp 7 was reached.

Edit: Just to add there was no coronal hole boost to the solar Wind so the storm was almost entirely attributable to the CME.

It's happened again. Except with just the solar wind this time, not a CME. A weak wind was expected to impact a day or so ago but never arrived, suggesting it was a weak wind with low speed. A weak wind usually doesn't register much on the Kp index and so this is what was forecast by NOAA (forecast.jpg).

They have had to revise their forecast. Updated since this morning. (forecast revised.jpg).

Basically small scale and normal solar events have had slightly larger than expected geomagnetic impacts. Two recent occurrences does not make a trend but keep an eye.

Latest CMEs didn't impact as hard as predicted so no, no trend yet it seems.

Cycle 25 is starting to ramp up now anyway in the last couple of months.
