Below is the NOAA forecast for HRPO's planned viewing time of 12pm to 2pm...
precipitation potential, 74%
sky cover, 98%
relative humidity, 94%
temperature, 18˚C
surface wind, W 13 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time both the transparency rating and the seeing rating will be "too cloudy to forecast" (0 out of 5).

There will be no solar viewing and HRPO will close at 12pm.

The 15 January 2022 day rating is...

There are currently four Active Regions on the Earth-facing side of the Sun.

AR 2934 has a single large spot with good transition zone. AR 2935 has one medium- and one small-sized spot. AR 2936 has an irregular collection of at least five spots with widespread plage. AR 2937 has two irregular-bordered medium-sized spots, along with a tiny speck of a spot.

Craig Brenden sent HRPO an alert regarding the high solar activity this week.

ARs 2934 and 2935 and rotating out of view, and AR 2937 is gone. AR 2936 is going strong with two very nice sunspot with dark centers. It is now joined by AR 2938 (little activity), and by ARs 2939 and 2940, both with extension spot-and-plage areas.

HRPO's next planned solar viewing session is on the 26th, but the facility programs special public viewing of the Sun when extensive surface activity accompanies a radio blackout, a solar radiation storm or a geomagnetic storm.

There are three visible Active Regions on the Earth-facing side of the Sun today. AR 2953 has only a string of puny spots, but ARs 2954 and 2955 (which have rotated into view as of a few days ago) have nice medium-sized spots with dark centers.

ARs 2954 and 2955 have been joined by puny 2956, substantial 2957 (two slightly smaller-than-medium sunspots together with three or four tiny ones) and 2958 (a chain of two small sunspots with very faint plage)...

I just observed 2954, 2955 and 2957 about twenty minutes ago. This is some moderate activity. As such a Solar Viewing Special Session is programmed at HRPO for 1:30pm to 3:30pm on Friday 4 March.

In the almost four weeks since that last group of Active Regions either gave up the ghost or rotated out of view, the Earth-facing side of the Sun now has a new production of sights. AR 2974 has one lone small spot. AR 2975 is fascinating, with a horseshoe archipelago of dark with smaller locations of note on three sides of the horseshoe. AR 2976 has the largest sunspot I've seen this year; it has a dark center elongated west-east. (2975 has a smaller, though still big, spot). AR 2978 is just rotating into view: a good-sized spot surrounded by plage.

I viewed and sketched the Sun at 48x with a 6" Orion Skyquest Dobsonian. (James and Judah looked, too.) I saw all but 2974. Anyone interested in seeing this action should make the attempt within the next forty-eight hours.
