太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with a few C-class flares recorded. The largest flare was a C2.5 flare (SIDC Flare 7939), peaking at 13:03 UTC on June 13, associated with a filament eruption near S21W73. There are currently four numbered active regions on the visible solar disk. A new region emerged in the northeastern hemisphere and was numbered SIDC Sunspot Group 894 (NOAA Active Region 4468, N10E48; magnetic type beta), but it remained quiet. The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares very likely and a small chance of M-class flares.

日冕物質拋射

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

太陽風

Over the past 24 hours, solar wind parameters (ACE and SOLAR-1) were indicative of a probable mixture of the waning influence of the high- speed stream from the equatorial negative polarity coronal hole SIDC Coronal Hole 147 and the glancing-blow arrival of the ICME associated with the June 11 CME (SIDC CME 675). The solar wind speed decreased from about 620 km/s to approximately 470 km/s. The interplanetary magnetic field was weak, below 7 nT. The magnetic field orientation was predominantly in the negative sector, with the field directed towards the Sun. A gradual return to slow solar wind conditions is mostly expected over the next 24 hours, with a chance of weak enhancements from late on June 14 due to a possible glancing-blow arrival from the June 12 CME (SIDC CME 676).

地磁

Geomagnetic conditions reached active levels globally (NOAA Kp = 4) between 18:00 and 21:00 UTC on June 13. Locally over Belgium, quiet to unsettled conditions were observed (K-Bel = 1 to 3). Mostly quiet to unsettled geomagnetic conditions are expected over the next 24 hours, with a chance of active conditions and isolated minor storm periods from late on June 14 due to a possible glancing blow arrival from the June 12 CME (SIDC CME 676).

質子通量水平

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10pfu threshold level over the past 24 hours and is expected to remain so over the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux, as measured by GOES-19, exceeded the 1000 pfu alert threshold between 12:45 UTC and 16:50 UTC on June 14, reaching a maximum value of 1519 pfu. The greater than 2 MeV electron flux may exceed the alert threshold again over the next 24 hours. The electron fluence was at normal to moderate levels and is expected to remain at these levels over the next 24 hours.
