      point. It won't matter where a charge was obtained 50
      miles from the storm--only whether there is, underneath
      that cirrus cloud, an electrical field, like a charge
      plate on a capacitor, or a balloon rubbed near a facet,
      whether that cirrus cloud will move or not. Further, I
      think it is important that we are talking about low
      gravity and whether the cirrus is sustained under cloud
      wieghted conditions 75 miles or 50 miles--by then any
      local variance of particle size or charge would have
      been sorted out. Finally, I am inclined to think that
      because we are talking about ice crystals, the shape or
      form of the cloud matters, such that small uniform
      changes brought on by electric fields just by merely
      flattening out a cloud over a distance would enhance its
      ability to reflect back IR light! Think about it. It just
      wouldn't take much.

        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
