The K7RA Solar Update

Our exciting period of nearly daily sunspot activity ended with the first spotless day on November 23 and the Sun has been blank since then. A look at the STEREO image shows a bright active area, perhaps five days over the eastern horizon, but we don’t know if that will give us sunspots or not. Sunspot numbers for November 19-25 were 30, 31, 14, 13, 0, 0 and 0 with a mean of 12.6. The 10.7 cm flux was 76.7, 76.2, 75.8, 76.3, 75.7, 74.7 and 74.2 with a mean of 75.7. The estimated planetary A indices were 2, 1, 8, 4, 0, 6 and 5 with a mean of 3.7. The estimated mid-latitude A indices were 0, 2, 6, 2, 0, 3 and 4 with a mean of 2.4.
