Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours. The largest flare was a C1.9 flare (SIDC flare 7822) peaking on June 1 at 21:53 UTC. There are currently 9 numbered regions on the disk. SIDC Sunspot Groups 860 and 885 (NOAA Active Regions 4455 and 4457) are the largest and most complex regions on disk (magnetic type beta). The remaining regions are all simple and mostly quiet. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares probable and possible isolated M-class flares.

Vyhazování koronální hmoty

No Earth directed CMEs were detected in the available coronagraph imagery.

Koronální díra

An equatorial, positive polarity coronal hole (SIDC Coronal Hole 166) continued to cross the central meridian.

Solární bouře

Over the past 24 hours, the solar wind parameters reflected the waning influence of the high speed stream from the negative polarity coronal holes, which crossed the central meridian on May 27 and May 28, respectively. The solar wind speed decreased from 550 kms to around 400 km/s. The total magnetic field ranged between 3 and 8 nT. Bz had a minimum of -5 nT. The interplanetary magnetic field phi angle was mostly in the negative sector (directed away from the Sun). Slow solar wind conditions are expected over the next 24 hours.

Geomagnetismus

The geomagnetic conditions were at quiet to unsettled levels globally (NOAA Kp 3) and at quiet to active levels locally (K Bel 4). Quiet conditions are expected over the next 24 hours.

Úrovně protonového toku

The greater than 10 MeV proton flux was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, was below the 1000 pfu threshold. The greater than 2 MeV electron flux is expected to be below this threshold over the next 24 hours. The electron fluence was at normal levels and is expected to be at normal levels for the next 24 hours.
