Güneş Aktif Bölgeleri ve parlama

The solar flaring activity was at low levels over the past 24 hours with only C-class flares identified. A total of 6 numbered sunspot groups were identified on the visible solar disk. The strongest activity were two C1.3 flares (SIDC Flare 4723 and SIDC Flare 4725), peak time 03:15 UTC and 11:01 UTC on June 22. The flares were produced by SIDC Sunspot Group 523 (NOAA Active Region 4114) and SIDC Sunspot Group 526 (NOAA Active Region 4117) respectively. SIDC Sunspot Group 523 remains the most complex active region (magnetic type beta-gamma) and is now approaching the west limb. The solar flaring activity is expected to be at low levels over the next 24 hours, with very likely C-class flares and 35% chances for M-class flaring.

Koronal Kütle Atılımı

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

Koronal delikler

Part of a re-current negative-polarity mid-latitude coronal hole (SIDC Coronal Hole 116) has reached the central meridian on June 22. High speed stream emanating from this coronal hole might impact the Earth later on June 25.

Güneş rüzgarı

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) remained under the mild influence of a high speed stream from a large positive-polarity coronal hole (SIDC Coronal Hole 104). The interplanetary magnetic field (B) reached a maximum value of 9.8 nT with a minimum Bz of -7.1 nT. The solar wind speed varied mostly between 450 km/s and 600 km/s, reaching a maximum of 626 km/s. The B field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind conditions are expected to continue to be under a mild influence of a high speed stream over the next days.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours were quiet to active. Quiet to active conditions are expected for the next 24 hours as the Earth remains under a mild influence of a high speed stream.

Proton akı seviyeleri

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

Jeostatik yörüngedeki elektron akıları

The greater than 10 MeV GOES 19 electron flux briefly exceeded the 1000 pfu threshold over the last 24 hours and might briefly exceed the threshold again over the next 24 hours. The 24-hour electron fluence was at the nominal levels and is expected to remain so in the next 24 hours
