Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was very low over the past 24 hours. The X-ray flux was below C level. A total of 2 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 825 (NOAA Active Region 4419) is the largest and most magnetically complex (Beta-Gamma) regions on disk. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely and a small chance for M-class flares.

Koronalny wyrzut masy

A Coronal Mass Ejection (CME) was observed erupting towards the north-east, in LASCO-C2 data around 16:00 UTC on April 19. This CME is associated with a filament eruption seen in SDO/AIA 304 in around 15:15 UTC on April 19, with an estimated speed of 378 km/s. Analysis of this CME is ongoing.

Wiatr słoneczny

Over the past 24 hours the solar wind parameters were under the waning influence of a high-speed stream associated with SIDC Coronal Hole 147. The solar wind speed ranged between 406 km/s to 522 km /s. The total interplanetary magnetic field ranged from 2 to 10 nT, with the Bz reaching a minimum of -8 nT. The phi-angle was mainly in the negative sector (directed towards the Sun), with periods in the positive sector. In the next 24 hours solar wind conditions are expected to remain enhanced.

Geomagnetyzm

The geomagnetic conditions reached active condition globally (Kp 4) and unsettled conditions locally (K BEL 3) in the last 24 hours. Active 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 GOES-18 and GOES-19 was above the 1000 pfu alert threshold in the past 24 hours. The flux is expected to fluctuate around the alert threshold over the next 24 hours. The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 was above the 1000 pfu alert threshold in the past 24 hours. The flux is expected to fluctuate around the alert threshold over the next 24 hours.
