Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the past 24 hours remained at low levels. There are seven numbered regions on the visible solar disc with NOAA AR 3828 (beta-gamma) and NOAA AR 3825 (beta- gamma-delta) being the most complex ones. NOAA AR 3831 (beta-delta) has exhibited an increase in complexity of its underlying magnetic field configuration and NOAA AR 3827 (beta) has exhibited some decay. Two new active regions were numbered, namely NOAA AR 3833 (beta) and NOAA AR 3834 (beta), and have produced some low levels of activity. NOAA AR 3824 has continued to contribute to the low levels of activity from behind the west limb. The solar flaring activity is likely to be at low levels over the coming days with 35% chances of M-class flares and 5% chances for isolated X-class flaring.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24 hours.

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) have registered background slow solar wind regime. The interplanetary magnetic field peaked at 7.3 nT with a minimum Bz of - 4.4 nT. The solar wind velocity varied in the range of 344 km/s to 483 km/s. The B field phi angle has switched from the positive to the negative sector (directed towards the Sun). The solar wind conditions are expected to continue to be predominantly at slow background solar wind in the upcoming days with chances of a weak connection to a mild high speed stream related to a positive polarity coronal hole.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Mostly quiet to unsettled geomagnetic conditions with small chances for isolated active periods are expected over the next days.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux has been at nominal levels and is expected to remain so over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 16 and GOES 18 has exceeded the 1000 pfu threshold for a short period over the past 24 hours and is expected to exceed the threshold over the next 24 hours. The 24h electron fluence was at the border of nominal to moderate levels and is expected to remain so over the next 24 hours.
