Report of Solar and Geophysical Activity 16 Feb 2012
IA. Analysis of Solar Active Regions and Activity from 15/2100Z
to 16/2100Z: Solar activity was at very low levels. The disk and
limb were quiet and stable. No Earth-directed CMEs were observed
during the period.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a chance for C-class activity for the next three days (17 -
19 February).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was at quiet to active levels. ACE solar wind
velocities varied between 350 to 400 km/s while the Bz component of
the interplanetary magnetic field was mostly northward to +5 nT.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet levels on day one (17 February)
through late on day two (18 February). Late on day two and through
day three (19 February), field activity is expected to increase to
quiet to unsettled levels, with isolated active levels, due to
recurrent coronal hole high speed stream effects.
