Solar Activity

.24 hr Summary...
Solar activity continued at low levels. Region 4465 (N08W04, Cao/beta)
developed a few rudimentary leader spots, and new Region 4468 (N10E46,
Cro/beta) was numbered this period. The remaining regions were either
stable or in decay. The strongest flare of the period was a C2.5/Sf at
13/1309 UTC associated with a filament eruption near S21W73. The
subsequent CME, first observed in LASCO C2 imagery off the SW at 13/1326
UTC, is expected to miss Earth.
 
.Forecast...
Solar activity is expected to remain at low levels through 16 Jun, with
a slight chance for M-class (R1-R2/Minor-Moderate) flares.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels, with a peak
flux of 1,519 pfu. The greater than 10 MeV proton flux remained at
background levels.

.Forecast...
The greater than 2 MeV electron flux is likely to reach high levels on
14-16 Jun. The greater than 10 MeV proton flux is expected to continue
at background levels through 16 Jun.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected the continued influence of a negative
polarity CH HSS, with some lingering CME enhancements early in the
period. Total field strength reached 7 nT, and the Bz component varied
between +/-5 nT. Solar wind speeds gradually decreased from a peak near
625 km/s early in the period to a low of around 475 km/s by the end of
the period.

.Forecast...
The solar wind environment is expected to remain mildly enhanced over
14-15 Jun under continued, but waning -CH HSS influences. An additional
enhancement is likely on 16 Jun due to the anticipated glancing-blow
arrival of a CME from 12 Jun.

Geospace

.24 hr Summary...
The geomagnetic field was at mostly quiet to unsettled levels, with an
isolated active period, under -CH HSS and CME influences.

.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels,
with a chance for active conditions, on 14-15 Jun as -CH HSS influences
slowly diminish. Periods of active conditions are likely on 16 Jun due
to the anticipated glancing-blow arrival of a CME that left the Sun on
12 Jun.
