Average daily sunspot number plunged from 182.4 to 107, while
average solar flux dropped from 196.4 to 162.4. If I had not changed
the 343.1 to 165, solar flux average would have been 187.9, more
than 25 points higher than what we report here.
Six new sunspots emerged over the week, one on February 16, one each on February 18 and 19, and three more on February 20, then one day
after the end of the reporting week, on February 23, two more sunspot groups appeared.
The solar flux prediction for the next month shows a peak value of 180 for March 7-13.
Predicted values are 148 on February 24, 146 on February 25-27, 142 on February 28, 140 on March 1-2, 145, 150, 155, and 165 on March
3-6, 180 on March 7-13, then 175 and 170 on March 14-15, 160 on March 16-17, then 155, 160, 150, 140 and 135 on March 18-22, 125 on
March 23-24, 130 on March 25, then 140 on March 26-28, 145 on March 29-30, then 150, 155 and 165 on March 31 through April 2. Beginning
on April 3, predicted flux values are back to 180, continuing into the following week.
Predicted planetary A index is 10 on February 24-25, then 12, 18, 20, 16 and 10 on February 26 through March 2, 5 on March 3-4, then

Sunspot numbers for February 16 through 22, 2023 were 101, 86, 109, 112, 135, 106, and 100, with a mean of 107. 10.7 cm flux was 163.2,
165, 167.2, 169, 159.8, 160.9, and 151.9, with a mean of 162.4. Estimated planetary A indices were 24, 6, 6, 7, 8, 17, and 6, with a
mean of 10.6. Middle latitude A index was 21, 4, 5, 4, 6, 15, and 4, with a mean of 8.4.
