太陽活動區和耀斑

A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. They all have simple alpha or beta magnetic field configuration, and have only produced minor C-class flaring in the past 24 hours. The largest flare was a C1.2 flare peaking on June 17 at 05:20 UTC, which was produced by SIDC Sunspot Group 870 (NOAA Active Region 4465).

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. SIDC Coronal Hole 169 (equatorial coronal hole with a positive polarity) is currently crossing the central meridian.

太陽風

The ICME corresponding to the 12 June CME arrived to the Earth early on 17 June. As expected, the effect of the ICME was weak with a magnetic field reaching 12 nT (with Bz mostly positive) and a speed around 415 km/s. The arrival of a fast solar wind stream, from SIDC Coronal Hole 168 could be expected in the next 24 hours; however, due to the coronal hole's limited size, any impact is expected to be mild.

地磁

Geomagnetic conditions were quiet at planetary levels (Kp up to 2.33) and reached unsettled conditions at local levels (K_Bel up to 3). The possible arrival of a mild high speed stream may increase geomagnetic conditions.

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.
