Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C3.8 flare (SIDC Flare 4823) peaking on July 10 at 06:42 UTC, which was produced by SIDC Sunspot Group 551. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 522 (NOAA Active Region 4136) and SIDC Sunspot Group 525 (NOAA Active Region 4135) are the largest regions on disk, and both have a Beta-Gamma magnetic configuration. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. Further analysis of a CME observed at 16:00 UTC on July 9 in LASCO-C2 data, associated with a filament eruption seen in SDO/AIA 304 and 194 at 06:36 UTC on July 09 show that it is expected to miss the Earth.

Dziury koronalne

Returning SIDC Coronal Hole 104 (low to mid latitude coronal hole with a positive polarity) started to cross the central meridian on July 08 and is continuing to cross the central meridian.

Wiatr słoneczny

Over the past 24 hours, the Earth was under the slow solar wind regime. The solar wind speed ranged from 380 km/s to 460 km/s. The total interplanetary magnetic field ranged from 0 nT to 4 nT, with the Bz component reaching a minimum of -4 nT. The phi-angle was mainly in the negative sector (directed towards the Sun) until 05:02 UTC on July 10 when it switched to the positive sector. Slow solar wind conditions are expected for the next 24 hours.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally quiet (Kp 1-2) and quiet to unsettled locally (K BEL 1-3). Quite too unsettled conditions are expected for the next 24 hours.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellite, crossed the 1000 pfu threshold at 14:30 UTC on July 09 and has fluctuated around this threshold since then. The electron flux is expected to continue to fluctuate around this threshold in the next 24 hours. The 24-hour electron fluence was at moderate levels and is expected to remain at moderate levels over the next 24 hours.
