Last week the average daily sunspot number increased from 3.7 (at the end of January) to 10.3 and average solar flux from 69.1 to
72.5. Average planetary A index decreased modestly from 6.3 to 4.4, while average mid-latitude A index (measured at one location, in
Virginia) decreased from 4.9 to 3.6.
The heightened activity should continue over the next week.
Predicted solar flux is 78 on February 9-10, 76 on February 11-12,
74 on February 13-14, 72 on February 15-16, 70 on February 17-22, 69
on February 23-28, 70 and 71 on March 1-2, 72 on March 3-14, 71 on
March 15, 70 on March 16-21, and 69 on March 22-25.
Predicted planetary A index is 8 on February 9, 5 on February 10-16, then 8, 10, 5, 8, 10, and 8 on February 17-22, 5 on February 23
through March 13, then 8, 12, 8, 10, 5, 8, 10 and 8 on March 14-21 and 5 on March 22-25.
Sunspot numbers for February 1-7, 2018 were 0, 11, 0, 11, 13, 17, and 20, with a mean of 10.3. 10.7 cm flux was 69, 68.8, 69.2, 73,
74, 76.9, and 76.6, with a mean of 72.5. Estimated planetary A indices were 4, 4, 3, 3, 8, 5, and 4, with a mean of 4.4. Estimated
mid-latitude A indices were 2, 3, 2, 3, 8, 4, and 3, with a mean of 3.6.
