Teased again, on Wednesday, April 22 we saw sunspot 1015 fade away, just as it was about to slip over our Sun's western limb. It emerged only briefly, late on April 21, and by Thursday it had disappeared. Sunspot numbers for April 16 through 22 were 0, 0, 0, 0, 0, 0, and 11 with a mean of 1.6. The 10.7 cm flux was 69.9, 69.8, 69.9, 70.1, 69.8, 71, and 71.1 with a mean of 70.2. The estimated planetary A indices were 6, 5, 8, 4, 4, 5 and 4 with a mean of 5.1. The estimated mid-latitude A indices were 3, 4, 8, 4, 3, 3 and 2 with a mean of 3.9. The outlook for the near term is more of the same, quiet conditions. Geophysical Institute Prague predicts quiet conditions for April 24-30. The US Air Force and NOAA predict a nice quiet planetary A index of 5 until May 6-9, when they expect to see a planetary A index of 15, 8, 8 and 8.
