Solar Activity

.24 hr Summary...
Solar activity remained at low levels. The majority of the C-class
activity originated from the eastern and western limbs of the Sun. The
strongest flare was a C5.5 flare at 23/2204 UTC. Region 4441 (N08W78,
ESO/beta) was responsible for a C2.8 flare at 23/1954 UTC. This event
also produced a Type II radio sweep (est. 932 km/s). The CME signatures
identified in available coronagraph imagery were associated with
activity on or behind the Suns limb. No Earth-directed components were
suspected.

Newly numbered Region 4447 (S15E32, Dao/beta) was a separation of the
northern spots from Region 4444 (S21E36, Hsx/alpha).

.Forecast...
Solar activity is expected to remain at low levels, with a chance for
isolated M-class flares (R1-R2/Minor-Moderate) on 24-26 May, primarily
due to the flare potential of Region 4441 and Region 4446.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit remained at
moderate to high levels, reaching a peak level of 4,016 pfu at 23/1555
UTC. The greater than 10 MeV proton flux at geosynchronous orbit
remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to remain at moderate
to high levels on 24-25 May before returning to low to moderate levels
on 26 May. The greater than 10 MeV proton flux is expected to remain at
background levels through 26 May.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected near-background conditions. Wind speeds
were between 290-330 km/s, total magnetic field strength varied from 3-5
nT. The phi angle was predominantly in a negative orientation.

.Forecast...
Primarily ambient conditions are expected for 24-25 May under a
background solar wind regime. Late on 26 May, enhancements to the solar
wind environment are possible with the anticipated onset of a negative
polarity CH HSS.

Geospace

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

.Forecast...
Mostly quiet levels are anticipated on 24-25 May under a near-background
solar regime. Periods of unsettled conditions are possible, with a
chance for an isolated active period, late on 26 May with the likely
onset of an approaching -CH HSS.
