Solar Activity

.24 hr Summary...
Solar activity remained at very low levels. A newly emerged active
region was numbered as 2123 (S13E51, Cro/Beta), but, like the other 3
regions, was inactive. No Earth directed CMEs were observed over the
period.

.Forecast...
Solar activity is expected to be very low with an increasing chance for
C-class flare activity (Below R1-Minor) over the next three days (24-26
Jul).


Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels and the greater than 10 MeV proton flux at geosynchronous
orbit was at background levels.

.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is expected
to be at normal levels and the greater than 10 MeV proton flux at
geosynchronous orbit is expected to remain at background levels (Below
S1-Minor) for the next three days (24-26 Jul).


Solar Wind

.24 hr Summary...
Solar wind continued at nominal levels over the period. Solar wind
speeds varied between 304 km/s and approximately 365 km/s, ending the
period just under 345 km/s. Total field ranged between 1 and 7 nT with
the Bz component variable between -6 nT and +4 nT. The Phi angle
transitioned from a negative (toward) orientation to positive between
23/1600-2000 UTC.

.Forecast...
Solar wind parameters are expected to remain near nominal conditions for
day one (24 Jul). High speed stream effects are expected to begin on
days two and three (25-26 Jul) as CH74 moves into a favorable position.


Geospace

.24 hr Summary...
The geomagnetic field was mostly quiet with isolated unsettled
conditions due to intermittent -Bz with a solar sector boundary
crossing.

.Forecast...
The geomagnetic field is expected to be mostly quiet for day one (24
Jul). Quiet to unsettled levels (Below G1-Minor) are expected on days
two and three (25-26 Jul) due to CH effects.
