Nothing with a solar viewer, but the Sunspotter easily showed ARs 2651 and 2653 and just barely 2652. 48x magnification in the filtered Orion 10" Dobsonian showed the three specks that constitute 2652 quite clearly.

Tony Phillips is quoting NOAA as saying there is a forty percent chance of geomagnetic storms this week. Gaseous material streaming from a coronal hole should hit our magnetic field tomorrow. As of this hour, there are no corresponding Active Regions.

A coronal mass ejection reached Earth about three hours ago--a full day ahead of time. The CME was quite weak, so if it does create any geomagnetic storm conditions, it won't be for a day or two.
