Solar Activity

.24 hr Summary...
Solar activity was at very low levels. Region 2715 (N08W01,
Dao/beta) was stable and inactive. Region 2713 (N05W58, Dao/beta)
exhibited slight growth during the period and was inactive. No
Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be very low all three days (22-24 Jun)
with a chance for C-class flares all three days.


Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels
and the greater than 10 MeV proton flux continued at background values.

.Forecast...
The greater than 2 MeV electron flux is expected to continue at normal
to moderate levels all three days (22-24 Jun) and the greater than 10
MeV proton flux is expected to remain at background values.


Solar Wind

.24 hr Summary...
Solar wind parameters were at nominal levels. Total field strength
ranged primarily from 2 to 3 nT and the Bz component variations were
weak. Solar wind speed decreased to end of period speeds near 350 km/s.
The phi angle was positive.

.Forecast...
A slow solar wind regime is expected to continue the next two days
(22-23 Jun). Day three (24 Jun) is expected to see an enhancement due to
the arrival of a CIR ahead of a positive polarity CH HSS.


Geospace

.24 hr Summary...
The geomagnetic field was quiet.

.Forecast...
The geomagnetic field is expected to be quiet on days one and two (22-23
Jun). Day three (24 Jun) is expected to be quiet to unsettled due to the
anticipated CIR and CH HSS.
