No new sunspots yet, but a big surprise this week with aurora and a geomagnetic storm: Sunspot activity peaked around 0300-0900 UTC on Wednesday July 22, with K index as high as 6. The planetary A index for the day was 24. You can see the K index variation here. One nice result was aurora propagation on 6 meters. A week ago there wasn't any indicator of increased activity. If you go here and click on July 21, you can see that the forecast was modified more than once, but the highest forecast was an A index of only 15. There is a new sunspot trying to emerge today (July 24), but it looks to be from Solar Cycle 23.
