Solar Activity
.24 hr Summary...
Solar activity was at low levels. Region 4470 (N07E40, Dao/beta)
produced a C1.8/Sf flare at 18/1150 UTC, the strongest of the period.
Minor growth was observed in Region 4471 (N18E11, Dao/beta). Region 4465
(N07W62, Cso/beta) was mostly stable.
No Earth-directed CMEs were observed in available coronagraph imagery.
.Forecast...
Solar activity is likely to continue at low levels 19-21 Jun, with a
slight chance for M-class (R1-Minor) solar flares.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels and the
greater than 10 MeV proton flux remained at background values.
.Forecast...
The greater than 2 MeV electron flux is likely to continue reaching
high levels on 19 Jun. The greater than 10 MeV proton flux is expected
to remain at background levels.
Solar Wind
.24 hr Summary...
Solar wind parameters were at nominal levels. Total field strength was
between 2-8 nT. The Bz component reached as far south as -8 nT. Solar
wind speeds steadily declined from ~440 km/s to ~350 km/s by the
periods end. Phi angle transitioned from negative to positive after
~18/1750 UTC.
.Forecast...
Solar wind parameters are likely to contain minor enhancements through
21 Jun due to weak positive polarity CH HSS effects.
Geospace
.24 hr Summary...
The geomagnetic field was mostly quiet with an isolated unsettled
period.
.Forecast...
The geomagnetic field is likely to reach active levels on 19-20 Jun in
response to weak CH HSS influences. Unsettled conditions are likely on
21 Jun due to waning CH HSS effects.
