Last week's bulletin again mentioned briefly appearing sunspots and it happened again this week. For just two days, another Solar Cycle 23 spot appeared, number 1014. The latitude of the spot was consistent with an old and fading solar cycle. As this period of quiet Sun drags on, statistic based projections of a return to solar activity continue to be pushed out. Sunspot numbers for March 5-11 were 0, 12, 12, 0, 0, 0 and 0 with a mean of 3.4. The 10.7 cm flux was 69.2, 69.1, 69.1, 68.9, 69.1, 68.8, and 68.9 with a mean of 69. The estimated planetary A indices were 3, 2, 1, 8, 2, 3 and 3 with a mean of 3.1. The estimated mid-latitude A indices were 3, 0, 0, 7, 1, 3 and 2 with a mean of 2.3.

    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
