Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only five C-class flares identified. SIDC Sunspot Group 559 (NOAA Active Region [AR] 4143, Beta magnetic configuration) produced three of the flares, including the brightest, SIDC flare 4898, a C5 on 16 Jul at 03:58 UTC. SIDC Sunspot Group 558 (NOAA AR 4142, Beta-Gamma magnetic configuration) produced the rest of the flaring activity. C-class flares are expected for the next 24 hours.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Wiatr słoneczny

During the past 24 hours the Solar Wind (SW) conditions continued to be affected by the the High Speed Stream (HSS) that arrived on 11 July and is associated with SIDC Coronal Hole 104 (positive polarity). However, the effect is significantly subsided with the SW speed gradually decreasing from 730 km/s to 500 km/s . The interplanetary magnetic field (B) varied between 3 and 8 nT and its North-South component (Bz) fluctuated between -6 and 7 nT. The fast SW conditions are expected remain at the current levels in the next 24 hours.

Geomagnetyzm

The geomagnetic conditions were globally at quiet to unsettled levels (NOAA Kp 2- to 3) for most of the past 24 hours with the exception of active conditions on 16 Jul between 09:00 and 12:00 UTC. Locally the conditions were quiet to unsettled (K BEL 1 to 3) throughout the last 24 hours. For the next 24 hours the conditions are expected to remain at unsettled to quiet levels and possibly register active conditions for short intervals.

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is expected to remain so in the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES 19, was mostly above the 1000 pfu alert threshold during the past 24 hours. It is expected to remain above the alert level in the next 24 hours. The 24-hour electron fluence reached moderate levels since 15 Jul at 15:00 UTC. It is expected to remain at the current levels in the next 24 hours.
