There are now seven Active Regions on the Earth-facing side of the Sun. ARs 2979 and 2980 aren't contributing too much visually--yet. The main attraction, however, are 2976 and 2978. They are not massive, but they are close to it. Combined with the plage, this is extensive activity.

AR 2975 has exploded over a dozen times in the past twenty-four hours. One released coronal mass ejection is predicted to hit Earth' magnetic field Thursday, with a second CME (maybe even a third) arriving Friday.

HRPO personnel are expanding the solar viewing during Nano Days this Saturday; it will now run from 3pm to 5:30pm. However, anyone has his own safety equipment and wants to increase the likelihood of seeing all the good stuff should attempt a viewing within the next thirty-six hours.

Below is the NOAA forecast for HRPO's planned viewing time of 3pm to 5:30pm...
precipitation potential, 0%
sky cover, 14%
relative humidity, 49%
temperature, 25˚C
surface wind, E 11 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "average" (3 out of 5).

The 2 April 2022 day rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

There are currently three Active Regions on the Earth-facing side of the Sun. AR 2988 isn't contributing too much visually--yet. The main attractions are 2989 and 2990. They are rotating into view and may spawn sizable visual activity.

There was G1 and G2 activity in the past thirty hours, and G1 and G2 activity predicted for the next thirty hours. Anyone who has his own safety equipment and wants to increase the likelihood of seeing potential good stuff should attempt a viewing within the next thirty-six hours.

There are now four Active Regions on the Earth-facing side of the Sun. AR 2991 is one tiny sunspot. The main attractions are ARs 2993 and 2994, which are very close together. The three main sunspots there are fairly massive, with a string of tiny sunspots between them. AR 2995 is currently rotating into view.

Although it's been virtually overcast at HRPO, Amy Northrop obtained visual confirmation of 2993 and 2994 with a Sunspotter; this device has a fixed magnification of 56x. Due to this confirmation and the Level 3 Radio Blackout conditions experienced in the past twenty-four hours, HRPO personnel will conduct a special solar viewing session on Saturday 23 April from 1pm to 3pm. However, anyone has his own safety equipment and wants to increase the likelihood of seeing all the good stuff should attempt a viewing within the next forty-eight hours.

There are now four Active Regions on the Earth-facing side of the Sun. ARs 3006, 3008 and 3009 each have from three to five noticeable spots, with 3006 occupying the most surface area and having the largest sunspot.

The main attraction is AR 3007. The Sun is about 1.39 million kilometers across at the equator, and 3007 (by my rough calculations) spans about ten percent of a comparable distance. Four medium-sized spots, two sharing a transition zone, together with about thirteen small and tiny specks.

Sadly it has been mostly cloudy at HRPO this afternoon and so personnel cannot confirm visuals with equipment there.
