      Well, depending on whom you ask, we're either at solar minimum, at the
      beginning of solar minimum, or months away from it. Here's what we do
      know. 21 of February's 28 days were sunspot-free. According to
      Spaceweather.com, that marked the beginning of solar minimum. It
      should continue for several more months. However, I read a story
      today about how the solar minimum may be a year away, and that the
      next solar maximum may be a doozy!

      If the article is correct, the solar minimum is a year away, and the
      ramp-up for cycle 24 is going to be late in coming. The problem with
      that is you can't argue with the numbers and it's sort of hard to get
      less than zero, which is what we saw during a large part of February.
      Personally, I think we're going to start seeing the sunspot numbers
      rise by the end of the year. Time will tell.

      There's nothing really noteworthy to report in the way of current
      activity, so I'll just go straight into the current conditions.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 24
      SFI : 72 (I'll be interested to see if this drops below 70)
      A index : 3
      K index : 0

      Solar wind speed : 361.6
      Solar wind density : 3.0 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 7.4 nT
      IMF Orientation : 6.3 nT North

      GOES-12 Background X-ray Flux level : A0

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      Forecast for the next 24 hours :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to remain very low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled for the
      next three days. Isolated periods of active conditions are possible
      due to a favorably positioned coronal hole.

      Recent significant solar flare activity :
      None
