IA. Analysis of Solar Active Regions and Activity from 27/2100Z
to 28/2100Z: Solar activity was very low. The visible disk is
spotless. No flares occurred during the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was quiet to active. Active to unsettled
conditions were observed from 27/2100Z to 28/0900Z, associated with
a slight increase in solar wind velocity (up to 460 km/s) observed
at ACE. Activity declined to quiet levels for the remainder of the
period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the next three days (29-31 July).
