Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. The largest flare was a M1.4 flare (SIDC Flare 5430) peaking on September 05 at 01:16 UTC and the second largest flare was a M1.0 flare (SIDC Flare 5428) peaking on September 04 at 13:44 UTC, both were produced by SIDC Sunspot Group 624 (NOAA Active Region 4207). A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 624 (NOAA Active Region 4207) is the largest and most magnetically complex (Beta- Gamma) region on disk and produced most of the flaring activity in the last 24 hours. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Wiatr słoneczny

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged from 395 km/s to 537 km/s. The total interplanetary magnetic field ranged from 6 nT to 9 nT, with the Bz reaching a minimum of -6 nT. The phi-angle was mainly in the positive sector (directed away from the Sun), with periods in the negative sector. The solar wind conditions are expected to become disturbed in the next 24 hours, due to the expected arrival of high-speed streams associated with SIDC Coronal Hole 123 and SIDC Coronal Hole 128.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally and locally quiet to unsettled (Kp 1-3 & K BEL 1-3). Active to minor storm condition are expected for the next 24 hours.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites, were below the 1000 pfu threshold in the last 24 hours. The 2 MeV electron flux is expected to remain below the threshold during the next 24 hour. The 24-hour electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.
