      Things are pretty quiet this evening, which is in
      contrast to the unusually high activity that was seen
      throughout December and the first few days of the new year.
      Although it has been quiet since the tremendous X3 flare
      on Dec. 28, sunspot region 9767 still has the
      potential of unleashing at least an M-class flare, as does
      9773. There is a substantial coronal hole that is
      approaching the sun's central meridian, and it will likely be
      sending some high speed solar wind gusts our way towards
      the end of the week.<br><br>The current solar and

        On Feb 28th, the Interplanetary Magnetic Field
        swung to a strong south-pointing orientation. That,
        coupled with an elevated solar wind speed and density,
        triggered a G-1 class geomagnetic storm. The result was
        some high latitude aurora. See this link for a
        photgraph of aurora observed over Quebec :
        <a href=http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg target=new>http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg</a> . As of right now, there are 3 sunspot regions,
        namely 9839, 9842, and 9845, that appear to be capable
        of producing M-class flares. Regions 9839 and 9842
        are close to rotating out of view over the western
        limb of the solar disk. Sunspot region 9845, however,
        is close to the sun's central meridian. A rather
        large coronal hole is also approaching the sun's
        central meridian, and coming into an Earth-pointing
        position. High speed colar wind gusts are likely around the
        first of next week.<br><br>The current solar and
