Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 847 (NOAA Active Region 4420) is the largest and most magnetically complex region on disk (Beta-Gamma-Delta). SIDC Sunspot Group 805 (NOAA Active Regions 4384, 4408, 4413, 4425) has rotated on the visible solar disk and produced most of the flaring activity in the last 24 hours. The largest flare was a M1.3 flare (SIDC Flare 7501) peaking on April 26 at 00:23 UTC, and the second largest was a M1.1 flare (SIDC Flare 7494) peaking on April 25 at 14:30 UTC, which both were produced by SIDC Sunspot Group 805. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares very likely and a small chance for X-class flares.

Koronalny wyrzut masy

No Earth directed Coronal Mass Ejections (CMEs) were observed in the past 24-hours. Further analysis of the CME observed in LASCO-C2 data at 18:34 UTC on April 24 show that the CME is not expected to impact the Earth.

Wiatr słoneczny

Slightly enhanced solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged between 357 km/s to 501 km /s. The total interplanetary magnetic field ranged from 4 to 14 nT, with the Bz reaching a minimum of -13 nT. The phi-angle was in the positive sector (directed away from the Sun) with periods in the positive sector. The wind conditions are expected to become enhanced in the next 24 hours, due to the arrival of high-speed streams associated with SIDC Coronal Hole 157 and SIDC Coronal Hole 156 and a possible glancing blow arrival from a CME that left the Sun on April 24.

Geomagnetyzm

The geomagnetic conditions reached active conditions globally and locally (Kp 4 & k BEL 4) in the last 24 hours. Active to minor storm conditions are expected over the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV GOES proton flux was at background levels and is expected to remain at background levels over the next 24 hours.

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.
