Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate during the last 24 hours. Two M1 flares were detected, the first yesterday 12:14 UT from NOAA Active Region (AR) 3341 (magnetic type Beta) and the second picked today at 11:25 UT from NOAA AR 3342 (magnetic type Beta, Catania group 35). Numerous C-class flares were also produced, mainly from NOAA AR 3335 (magnetic type Beta, Catania group 33), 3340 (magnetic type Beta, Catania group 38), 3341, and 3342 in the last 24 hours. Further isolated M-class flaring activity is likely in the next 24 hours, mostly from NOAA AR 3341, 3342, the group of NOAA AR 3335 and 3336, or a yet- unnamed AR at S15E90.

Koronalny wyrzut masy

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

Wiatr słoneczny

The Solar Wind (SW) conditions were typical of the slow SW regime and stable during the last 24 hours. The SW speed ranged between 390 and 500 km/s in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 4 and 8 nT and its North-South component (Bz) ranged between -6 and 6 nT. The interplanetary magnetic field phi angle was predominately directed towards the Sun during the past 24 hours. The SW conditions are likely to register the arrival of a small High Speed Stream (HSS) in the next 24 hours.

Geomagnetyzm

Geomagnetic conditions were moderate to quiet globally (NOAA Kp 2- to 3) and active to quiet locally (K BEL 2 to 4) during the past 24 hours. They are expected to be at moderate to quiet levels both globally and locally for the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was marginally above the 1000 pfu threshold yesterday between 12:45 and 19:00 UT. It has remained below this level since and it is expected to increase again during the next 24 hours, but probably not much above the threshold level and only for a short period. The 24-hour electron fluence was at moderate levels during the last 24 hours and is expected to drop to nominal levels at some point in the next 24 hours.
