Сонячно-активні області та спалахи

The solar flaring activity has reached moderates levels over the past 24 hours. An M2.6 flare (SIDC Flare 7622), peak time at 15:14 UTC on May 07, was produced by a region from behind the east limb. A total of 4 numbered sunspot groups were identified on the visible solar disk. Two of the regions are simple (classified as magnetic type alpha) and have remained inactive. SIDC Sunspot Group 862 (NOAA Active Region 4433) currently located at S16E12, classified as magnetic type beta, has produced a C6.0 flare (SIDC Flare 7624) with peak time at 17:57 UTC on May 07. SIDC Sunspot Group 860 (NOAA Active Region 4432) has exhibited significant flux emergence and is currently classified as magnetic type beta-gamma. So far it has produced only a single isolated low C-class flare. The solar flaring activity is expected to be at low levels over the next 24 hours with very likely C-class flares and chances for isolated M-class flaring.

Корональні викиди маси

No other Earth-directed coronal mass ejection (CMEs) have been identified in the available coronagraph imagery over the past 24 hours.

Сонячний вітер

Over the past 24 hours the solar wind parameters (as measured by ACE at L1) have registered an anticipated co-rotating interaction region (CIR) arrival with a subsequent arrival of a mild high speed stream associated with a positive polarity coronal hole (SIDC CH 158). The magnitude of the interplanetary magnetic field (B) was substantially elevated, reaching a maximum value of 20.11 nT. The north-south (Bz) component was predominantly positive (northward) and registered a minimum value of -12.3 nT. The solar wind speed has increased to close to 600 km/s at present. The B field phi angle was predominantly in the positive sector (directed away from the Sun) reflecting the polarity of the geo-effective coronal hole. The solar wind parameters over the next 24 hours are expected to remain under the mild influence of the ongoing high-speed stream arrival.

Геомагнетизм

The geomagnetic conditions over the past 24 hours have been globally quiet to unsettled with active levels registered locally over Belgium between 19:00 and 22:00 UTC on May 07. Quiet to active conditions are expected for the next 24 hours and predominantly quiet to unsettled conditions are expected for May 09.

Рівні потоку протонів

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the 24 hours over the next 24 hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux as measured by GOES 18 and GOES 19 was close to, but below the 1000 pfu threshold over the past 24 hours and might exceed the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence was at nominal levels and is expected to remain so over the next 24 hours.
