There have been no new sunspots since the recent brief three-day appearance of quickly fading sunspot 1013 on February 24-26. It was another Solar Cycle 24 sunspot, but this is not too encouraging, considering how brief and weak it appeared. There are no predictions for new sunspots, but these events tend to occur suddenly. Sunspot numbers for February 26-March 4 were 12, 0, 0, 0, 0, 0 and 0 with a mean of 1.7. The 10.7 cm flux was 69.9, 68.9, 70.6, 69.4, 69.2, 69.1 and 69.7 with a mean of 69.5.The estimated planetary A indices were 2, 8, 5, 3, 2, 5 and 7 with a mean of 4.6. The estimated mid-latitude A indices were 2, 7, 4, 2, 0, 5 and 5 with a mean of 3.6.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
