Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flare identified. The largest flare was a M2.37 flare peaking on July 12 at 08:30 UTC, which was produced by SIDC Sunspot Group 553 (NOAA Active Region 4140). A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 522 (NOAA Active Region 4136) is the largest region on disk and has a Beta-Gamma-Delta magnetic configuration SIDC. Sunspot Group 553 (NOAA Active Region 4140) has rotated on disk and produced most of the flaring activity in the last 24 hours. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Koronal Kütle Atılımı

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

Koronal delikler

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.

Güneş rüzgarı

Over the past 24 hours the solar wind conditions at Earth were disturbed, due to a high-speed stream (HSS), associated with SIDC Coronal Hole 104. The solar wind speed ranged from 420 km/s to 518 km/s. The total interplanetary magnetic field ranged from 8 nT to 14 nT, with the Bz component reaching a minimum of -9 nT. The phi-angle was mainly in the positive sector (directed away from the Sun), with periods in the negative sector. The solar wind conditions are expected to remain disturbed in the next 24, due to the influence of the HSS.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours reached active conditions globally and locally (Kp 4 & K BEL 4). Active conditions are expected for the next 24 hours.

Proton akı seviyeleri

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.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites, were below the 1000 pfu threshold in the last 24 hours. During the next 24 hours, there’s a chance that the electron flux exceeds the 1000 pfu threshold due to the influence of the HSS. The 24-hour electron fluence was at started the period at moderate levels and decreased to nominal levels. The electron fluence is expected to return to nominal over the next 24 hours.
