Solar Activity
.24 hr Summary...
Solar activity was very low and no sunspot groups were present. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar activity is expected to remain very low 24-26 Jul as no sunspot groups or active regions of interest are present.

Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was normal and the greater than 10 MeV proton flux continued at background values.
The greater than 2 MeV electron flux is expected to remain normal, with a chance for moderate levels 24-26 Jul. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind
.24 hr Summary...
Solar wind parameters indicated a mildly disturbed state. Total IMF strength varied from 2 to 6 nT and the Bz component underwent primarily weak deviations. Solar wind speed ranged primarily from 375-435 km/s. The phi angle was predominantly in a negative sector most of the period, but underwent brief excursions into a positive orientations.
A near ambient, background-like solar wind environment is expected to dominate 24-26 Jul. However, occasional mild enhancement is possible due to likely HCS proximity.

.24 hr Summary...
The geomagnetic field was quiet.
The geomagnetic field is expected to be predominantly quiet 24-26 Jul, with a few unsettled occurrences likely.
