Aktywne obszary słoneczne i rozbłyski

A total of 3 numbered sunspot groups were identified on the disk over the past 24 hours. Flaring activity has been very low, no C-class flares detected in the past 24 hours. The most complex region remains SIDC Sunspot Group 825 (NOAA Active Region 4419) currently located at N14W03 with a Beta-Gamma magnetic configuration. Low activity can be expected in the next 24 hours, with C-class falres likely.

Koronalny wyrzut masy

A CME was observed erupting towards the SE, first by LASCO C2 at 09:00 UTC on 18 February. This CME originated on a filament eruption centered around S40E40, with a speed around 350 km/s and angular of about 60 degrees, the bulk of the material was travelling to the south and will therefore most likely miss the Earth.

Dziury koronalne

There is a large equatorial coronal hole with negative polarity in the western hemisphere (SIDC Coronal Hole 147).

Wiatr słoneczny

The Earth is still within the fast solar wind stream from SIDC Coronal Hole 147. The solar wind speed rose to close to 600 km/s, interplanetary magnetic field reached 18 nT with Bz down to -14 nT. Currently the speed is around 520 km/s with an interplanetary magnetic field magnitude of about 7 nT. Similar fast solar wind conditions can be expected for the next 24 hours.

Geomagnetyzm

Geomagnetic conditions have reached moderate storm levels at planetary scale with Kp up to 6- and active levels locally with K_Bel up to 4. More disturbed periods are expected in the next 24 hours as the fast solar wind stream continues to pass.

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10 pfu threshold level 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 GOES-18 and GOES-19 was below the 1000 pfu alert threshold in the past 24 hours. The flux is expected to increase above the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
