Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low but frequent over the past 24 hours, with more than 10 C-class flares identified. SIDC Sunspot Group 469 (NOAA Active Region [AR] 4079, Beta- Gamma magnetic configuration) produced the majority of the flares. SIDC Sunspot Group 492 (NOAA AR 4082, Beta-Gamma magnetic configuration) emitted the brightest flare (SIDC Flare 4334) of the last 24 hours, a C7 on 8 May at 11:41 UTC. A C3 flare (SIDC Flare 4331) is associated with the N32E35 solar location that is not part of an AR. A yet-unnamed AR at S20E90 also emitted a flare on 7 May at 12:08 UTC. The SIDC Sunspot Groups 469 and 492 are expected to continue there flaring activity and there is a chance of them emitting one or more M-class flares. The unnamed AR at the East limb is also possible to produced isolated C-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. A CME seen in LASCO-C2 images as launched on 7 May at 10:36 UTC is associated with a filament eruption and is not expected to affect the Earth.

Wiatr słoneczny

The Solar Wind (SW) conditions have now returned to the slow SW regime. The SW speed dropped from 550 km/s to 400 km/s during the past 24 hours. In the same period the interplanetary magnetic field (B) varied between 3 and 12 nT, and its North-South component (Bz) fluctuated between -6 and 5 nT. A High Speed Stream (HSS) is expected to arrive in the next 24 hours and there is a small chance of a glancing blow from a Coronal Mass Ejection (CME) on 9 May.

Geomagnetyzm

The geomagnetic conditions registered globally and locally quiet to unsettled levels (NOAA Kp 1 to 3 and K BEL 2 to 3). They are expected to remain at those levels during the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at nominal levels over the past 24 hours and is likely to remain so in the next 24 hours. Nevertheless, there is a small chance that a proton event might occur during the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 19 was above the 1000 pfu threshold during the past 24 hours, with a peak value at 13000 pfu. It is expected to remain well above the alert level during the next 24 hours. The 24-hour electron fluence continued to be at high levels during the past 24 hours. It is expected to remain at high levels in the next 24 hours.
