Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 178 Issued at 2200Z on 26 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was low. Region 1512 (S16E25, Dai/Beta)
was in a gradual growth phase during the period and produced a C1
x-ray flare as well as occasional optical subflares. New Region 1513
(N16E71, Hax/Alpha) was numbered and produced a C1/Sf flare. No
Earth-directed coronal mass ejections were observed during the
period.
IB. Solar Activity Forecast: Solar activity is expected to be low
through the period (27 - 29 June).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet to unsettled levels with active to
minor storm periods detected at high latitudes. This activity was
associated with a minor increase in solar wind speeds (peak 496 km/s
at 26/0455Z) coupled with intermittent periods of southward IMF Bz
(maximum southward deflection -7 nT at 26/0113Z).
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet levels during days 1 - 2 (27 - 28
June). Field activity is expected to increase to quiet to unsettled
levels on day 3 (29 June) with a chance for active levels due to the
arrival of a co-rotating interaction region in advance of a coronal
hole high-speed stream.
