    It is so great to see some real Solar Cycle 24 sunspot activity this week. Instead of a phantom that pops into view one day and is gone the next, we have sunspot 1019, which has persisted for five days so far. Emerging on Sunday, May 31, the resulting dai

    That was a nice string of days showing a sunspot -- May 13-19 -- a whole week. Then it was gone, but a few days later on May 23, another Solar Cycle 24 sunspot emerged, this time in our Sun's southern hemisphere. But it was another of those phantom spots.

    Do sunspots matter? Many of us are surprised at how good conditions can be with zero sunspots; the weak solar wind and lack of flares and geomagnetic events likely have something to do with it. Many times during the more active solar periods, sunspots wer

    After weeks of little or no sunspots, it is nice to have something to report: Following multiple false starts, quick-fading spots and knots of magnetic activity that never progressed into actual darkened sunspots, new sunspot group 1017 emerged on Wednesd

    A Solar Cycle 23 spot appeared for two days -- April 29-30 -- in an area that soon rotated out of view. Sunspot numbers were 15 and 12, but for the last seven days, we haven't seen any spots. This may end soon -- we get the advance word because of the STE

    Teased again, on Wednesday, April 22 we saw sunspot 1015 fade away, just as it was about to slip over our Sun's western limb. It emerged only briefly, late on April 21, and by Thursday it had disappeared. Sunspot numbers for April 16 through 22 were 0, 0,

    Every day I check the 45 day forecast of planetary A index and solar flux from NOAA and the US Air Force. For quite some time now, the solar flux forecast has been the same: The projection shows 45 days of solar flux at 70, with no variation. I look at th

    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
