Solaraktive Regionen und Flares

A total of 4 numbered sunspot groups were identified on the disk over the past 24 hours. Flaring activity is low, with only minor C-class flares occurring. The largest flare was a C1.2 flare (SIDC Flare 7940) peaking on June 14 at 13:02 UTC, which was produced by SIDC Sunspot Group 891 (NOAA Active Region 4464). Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely.

Koronaler Massenauswurf

No Earth-directed CMEs were observed in the last 24 hours.

Koronale Löcher

SIDC Coronal Hole 168 (small equatorial coronal hole with a positive polarity) first reached the central meridian on June 13, we may observe its associated fast solar wind stream in 24 to 48 hours.

Sonnenwind

The Earth is inside slow solar wind, with speeds around 430 km/s and interplanetary magnetic field of 4 nT. Similar conditions can be expected for the next 24 hours. Nevertheless, a possible arrival of the CME from 12 June may create distrubed conditions.

Geomagnetismus

Geomagnetic conditions were quiet at planetary levels (Kp up to 2) and quiet to unsettled locally (K_Bel up to 3). Similar conditions can be expected for the next 24 hours.

Protonenflusswerte

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.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 was slightly 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 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.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 069, basierend auf 11 Stationen.
