Solaraktive Regionen und Flares

The solar flaring activity was at low levels, with several C-class flares recorded in the past 24 hours. The largest flare was a C6.6 flare, peaking at 11:43 UTC on Oct 29. The flare was associated with NOAA AR 3474 (beta-gamma class), which produced most of the flaring activity over the period. Low flaring activity was also produced by NOAA AR 3471. Other regions on the disc have simple configuration of their photospheric magnetic field (beta class) and did not show any significant flaring activity. The solar flaring activity is expected to be at low level over the next 24 hours with C-class flares likely and a low chance for isolated M-class flares.

Koronaler Massenauswurf

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

Sonnenwind

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) reflected the ongoing influence of the high-speed stream. The solar wind speed increased to values around 650 km/s. The interplanetary magnetic field magnitude decreased from about 12 nT to current values below 8 nT. The southward component of the interplanetary magnetic field fluctuated between -9 nT and 7 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Solar wind speed is expected to remain elevated for the next day with the ongoing high-speed stream influence.

Geomagnetismus

During the last 24 hours the geomagnetic conditions reached minor storm conditions globally and active conditions locally (NOAA KP: 3 to 5- and K Bel: 2 to 4). Mostly unsettled to active geomagnetic conditions are expected for the next 24 hours with chances for isolated minor to moderate storm periods due to HSS influence.

Protonenflusswerte

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

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It may cross the threshold over the next days due to the enhanced solar wind conditions. The 24 hour electron fluence was at normal levels and is expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 059, basierend auf 09 Stationen.
