  • 05/30/2008 | The K7RA Solar Update

    This week we saw only one sunspot, number 997, and only on Memorial Day, May 26. Alas, this was another sunspot left over from fading Solar Cycle 23 and its appearance was very brief. One day it weakly emerged, it quickly faded from view. The previous fiv

  • 05/23/2008 | The K7RA Solar Update

    This week several new sunspots appeared for five days, but they were all leftover spots from Solar Cycle 23, not new Cycle 24 spots. But this is okay, because at the sunspot minimum we appreciate any spots we can get. May 16-20 saw daily sunspot numbers o

  • 05/09/2008 | The K7RA Solar Update

    Again this week, we saw a new, but brief sunspot, sunspot 993. Judging from the polarity of the spot, it looks to be from new Solar Cycle 24; this spot was south of the solar equator, so it has the same polarity as any Cycle 23 spot that was north of the

  • 04/25/2008 | The K7RA Solar Update

    This week we had a couple of brief sunspot appearances -- 991 and 992 -- but they were both from Solar Cycle 23 and their emergence was fleeting. On Wednesday, April 23, the planetary A index rose to 32 due to a solar wind and south-pointing Interplanetar

  • 04/18/2008 | The K7RA Solar Update

    We saw a string of zero-sunspot days over the past couple of weeks, but this week saw a brief but significant sunspot that lasted only a couple of days. Sunspot 990 emerged as a tiny speck over April 14-15, but it was definitely a Solar Cycle 24 spot. Not

  • 03/28/2008 | The K7RA Solar Update

    It is exciting to see heightened solar activity one week into spring. Currently, three sunspots are visible: 987, 988 and 989. The consensus says that all seem to be old Solar Cycle 23 spots. But with the three sunspot groups so close to the Sun's equator
