SYNOPSIS OF TODAYS ACTIVITY
---------------------------

             of solar active regions and activity from 30/2100Z to
       31/2100Z: solar activity has been at low levels for the past 24 hours.
       The largest solar event of the period was a C8 event observed at
       31/1150Z. There are currently 8 numbered sunspot regions on the disk.

            Solar activity forecast: solar activity is expected to be low with
       a chance for M-class flares and a slight chance for an X-class flare on
       days one, two, and three (01 jan, 02 jan, 03 jan).
       

            field has been at quiet levels for the past 24 hours. Solar wind speed,
       as measured by the ace spacecraft, reached a peak speed of 426 km/s at
       31/0012Z. Total imf reached 6 nt at 31/0605Z. The maximum southward
       component of bz reached -4 nt at 31/0745Z.

            Geophysical activity forecast: the geomagnetic field is expected
       to be at quiet to unsettled levels on days one and three (01 jan, 03
       jan) and quiet to minor storm levels on day two (02 jan).
