Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at moderate levels, with multiple C-class flares and four M-class flares recorded in the past 24 hours. The largest flare of the period was an impulsive M2.3 flare, peaking at 08:42 UTC on Apr 15, associated with NOAA AR 3634 (beta class). NOAA AR 3639 (beta class), that produced three remaining M-class flares, was the main driver of the flaring activity observed over the past 24 hours. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours, with C-class flares probable and a chance of M-class flares.

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

Wiatr słoneczny

The solar wind parameters were indicative of a slow solar wind regime. The solar wind speed ranged between 330 and 380 km/s. The interplanetary magnetic field magnitude was below 5 nT. The southward component of the interplanetary magnetic field fluctuated between -4 nT and 4 nT. The magnetic field orientation was predominantly in the negative sector (field directed towards the Sun). Similar solar wind conditions are expected, with a chance for a weak enhancement on Apr 15 - Apr 16 due to the anticipated arrival of CMEs from Apr 11 and Apr 12.

Geomagnetyzm

Geomagnetic conditions were quiet both globally and locally (NOAA-Kp and K-BEL: 1 to 2) during the last 24 hours. Geomagnetic conditions are expected to remain mostly at quiet levels, with a chance of reaching active levels on Apr 15 - 16 due to potential CMEs arrivals.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, remained below the 1000 pfu threshold. It is expected to remain below the threshold during the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain at these levels for the following 24 hours.
