Atividade solar

Resumo das últimas 24h

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).

Previsão

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.

Partículas Energéticas

Resumo das últimas 24h

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.

Previsão

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.

Vento Solar

Resumo das últimas 24h

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.

Previsão

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.

Geoespaço

Resumo das últimas 24h

The geomagnetic field was at quiet levels.

Previsão

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.
