Сонячно-активні області та спалахи

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was a M2.4 flare (SIDC Flare 4813) peaking on July 08 at 04:17 UTC, which erupted behind the Suns east limb. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. All regions on disk have either an Alpha or Beta magnetic configuration. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Корональні викиди маси

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

Корональні діри

Returning SIDC Coronal Hole 104 (mid-latitude coronal hole with a positive polarity) started to cross the central meridian on July 08. The high-speed stream (HSS) from this coronal hole is expected to enhance the solar wind near Earth on July 11.

Сонячний вітер

In the past 24 hours solar wind conditions at Earth were disturbed, due to the waning influence of a high-speed stream (HSS), associated with SIDC coronal hole 111. The total interplanetary magnetic field ranged from 6 nT to a peak of 10 nT, with the Bz component reaching a minimum of -8 nT. The solar wind speed ranged from 496 km/s to 606 km/s. The phi-angle was mainly in the negative sector (directed towards the Sun) with periods in the positive sector. The solar wind conditions are expected to remain disturbed in the next 24 hours due to the ongoing influence of the HSS.

Геомагнетизм

The geomagnetic conditions over the past 24 hours reached active conditions globally (Kp 4) and were unsettled locally (K BEL 3). Quiet to active conditions are expected for the next 24 hours.

Рівні потоку протонів

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.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellite, remained below the 1000 pfu threshold over the past 24 hours. The electron flux is expected to remain below the threshold level over the next 24 hours. The 24-hour electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.
