Solar Activity
.24 hr Summary...
Solar activity reached low levels this period. The largest flare was a
C2.3 at 18/0405 UTC from Region 4489 (S07W01, Hax/alpha), which along
with Region 4491 (S11E36, Hrx/alpha), was stable throughout the period.
Multiple low-level C-flares originated from a source beyond view on the
E limb near N15. No Earth-directed CMEs were observed in available
coronagraph imagery.
.Forecast...
Solar activity is likely to reach low levels on 19-21 Jul, with a slight
chance for M-class flare activity.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels this period
with a peak flux of 1,170 pfu. The greater than 10 MeV proton flux was
steady at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
19-21 Jul. The greater than 10 MeV proton flux is expected to continue
at background levels through 21 Jul.
Solar Wind
.24 hr Summary...
Solar wind parameters continued at background levels. Total magnetic
field strength reached 5 nT, and the Bz component ranged between +/-3
nT. Solar wind speeds average around 325 km/s throughout the period.
.Forecast...
Background solar wind conditions are expected to prevail over 19-21 Jul.
Geospace
.24 hr Summary...
The geomagnetic field was quiet under an ambient solar wind environment.
.Forecast...
The geomagnetic field is expected to persist at quiet levels over 19-21
Jul.
