Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at moderate levels over the past 24 hours. A total of 7 numbered sunspot groups were identified on the visible solar disk. The strongest activity was a M1.0 flare (SIDC Flare 4717), peak time 17:40 UTC on June 20, produced by SIDC Sunspot Group 526 (NOAA Active Region 4117), now classified as magnetic type beta. SIDC Sunspot Group 523 (NOAA Active Region 4114) remains the most magnetically complex region, classified as magnetic type beta-gamma. The region has exhibited further decay and has produced only low C-class flaring over the past 24 hours. Low C-class flaring was produced from over the east limb, possibly from a returning active region SIDC Sunspot Group 508 (ex-NOAA Active Region 4099). The solar flaring activity is expected to be at low levels over the next 24 hours, with very likely C-class flares and 45% chances for M-class flaring.

Koronalny wyrzut masy

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

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) remained under the continuous influence of a high speed stream from a large positive-polarity coronal hole, which continues to partly reside on the central meridian. The interplanetary magnetic field (B) was mildly enhanced with a maximum value of 9 nT and a minimum Bz of -7 nT. The solar wind speed was smoothly varying between 430 km/s and 630 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.

Geomagnetyzm

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

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 at nominal levels over the next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 10 MeV GOES 18 electron flux briefly exceeded the 1000 pfu threshold over the last 24 hours and is expected to reach the threshold again over the next 24 hours. The greater than 10 MeV GOES 19 electron flux has remained under the 1000 pfu threshold and is expected to remain so 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.
