Bulletin

Solar flaring activity was low during the last 24 hours, with several C-class flares detected, the brightest of which was a C8 at 9 July 13:48 UT form NOAA Active Region (AR) 3047. More C-class flare activity is expected in the next 24 hours, mostly from NOAA AR 3053 and 3055 (Catania groups 72 and 78), while M-class activity remains possible.

A Coronal Mass Ejection (CME) can be seen in SOHO/LASCO C2 images, at 9 July 13:48 UT. This event was launched from the west solar limb and it is not geo-effective.

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. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

The Solar Wind (SW) parameters during the last 24 hours are typical of the slow SW regime. The SW speed was around 350 to 420 km/s. The magnetic field (Bt) varied between 2 and 10 nT, while its Bz component fluctuated from -8 to 7 nT in the last 24 hours. The interplanetary magnetic field phi angle is in the positive sector (directed away from the Sun) since 9 July 20:00 UT. The SW conditions are expected to remain in the slow SW regime the next 24 hours.

Geomagnetic conditions reached globally and locally moderate levels (NOAA Kp 1-3, K Doubres 0-3) during the last 24 hours. Conditions are expected to drop to quiet levels both globally and locally in the next 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 109, basierend auf 20 Stationen.
