Our Sun is still not producing any sunspots. As mentioned in previous bulletins, the peak of the last Solar Cycle was a double peak, so perhaps we are in the midst of an extended bottom. Sunspot numbers for August 7-13 were 0, 0, 0, 0, 0, 0 and 0 with a mean of 0. The 10.7 cm flux was 66.1, 65.5, 65.5, 65.6, 65.7, 65.2 and 65.3 with a mean of 65.6. Estimated planetary A indices were 4, 4, 18, 13, 7, 6 and 5 with a mean of 8.1. Estimated mid-latitude A indices were 3, 3, 16, 9, 6, 6 and 3 with a mean of 6.6.
