太陽活動區和耀斑

A total of 4 numbered sunspot groups were identified on the disk over the past 24 hours. Solar activity has been low with only C-class flares observed in the last 24 hours. SIDC Sunspot Group 870 (NOAA Active Region 4465) currently located at N09W24 has evolved into a beta-gamma magnetic field configuration. The largest flare was a C1.8 flare (SIDC Flare 7945) peaking on June 15 at 13:15 UTC, which was produced by SIDC Sunspot Group 870 (NOAA Active Regions 4441, 4465). More C-class flares can be expected in the next 24 hours.

日冕物質拋射

No Earth-directed CMEs were observed in the last 24 hours.

日冕洞

SIDC Coronal Hole 168 (equatorial coronal hole with a positive polarity) crossed the central meridian on June 13 and is now positioned on the western side of the Sun.

太陽風

The Earth remains within a slow solar wind stream, with speeds hovering around 410 km/s and an interplanetary magnetic field (IMF) of 5 nT. A fast solar wind stream originating from SIDC Coronal Hole 168 is anticipated to arrive within the next 24 hours; however, due to the coronal hole's limited size, any impact is expected to be mild. While the arrival of an ICME related to the June 12 CME remains possible, the probability is currently low.

地磁

Geomagnetic conditions were quiet at planetary and local levels (Kp and K_Bel up to 2). The possible arrival of a mild high speed stream and the CME from 12 June may increase geomagnetic levels.

質子通量水平

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10 pfu threshold level over the past 24 hours and is expected to remain so for 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-18 and GOES-19 was slightly above the 1000 pfu alert threshold in the past 24 hours. The flux is expected to fluctuate around the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
