The K7RA Solar Update
(Jan 9, 2009)
-- On Wednesday, January 7, a sunspot appeared very briefly in the lower right portion of the Sun's image. It was so brief that NOAA did not record it on the Space Weather Prediction Center's daily solar data chart for that day. Spaceweather.com reported a sunspot number of 11 for the day, and the magnetic polarity was consistent with a new Solar Cycle 24 spot. Today, January 9, there is another Solar Cycle 24 appearance, this time on the upper left of the image. Sunspot numbers for January 1-7 were 0, 0, 0, 0, 0, 0 and 0 with a mean of 0. The 10.7 cm flux was 68.9, 69.9, 69.5, 68.8, 69.2, 68.7 and 69 with a mean of 69.1. The estimated planetary A indices were 6, 3, 9, 4, 4, 3 and 3 with a mean of 4.6.
