Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours. The largest flare was a C9.0 flare (SIDC Flare 2659) peaking on November 19 at 17:28 UTC, which was produced by SIDC Sunspot Group 298 (NOAA Active Regions 3901). This region was the most active along with SIDC Sunspot Group 316 (NOAA Active Region 3897), which exhibited strong flux emergence, but is now rotating over the west limb. SIDC Sunspot Group 318 (NOAA Active Region 3898) currently located at S17W11 continued to develop and increase in size over the period and has a Beta magnetic configuration. The solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a chance for X-class flares.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24 hours.

Dziury koronalne

SIDC Coronal Hole 80 (mid-latitude coronal hole with a negative polarity) has begun to cross the central meridian on November 20.

Wiatr słoneczny

Over the past 24 hours the solar wind conditions predominantly reflected a slow solar wind regime. The interplanetary magnetic field continued to be slightly elevated, ranging between 2 and 13nT, with a minimum Bz of -10 nT. The solar wind speed ranged between 350 km/s and 420 km/s. The interplanetary magnetic field phi angle remained predominantly in the positive sector (directed away from the Sun). Slow solar wind conditions are expected to continue over the next 24 hours.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet to unsettled, with one local isolated active period (Local K Bel = 4). Quiet to unsettled geomagnetic conditions are expected for the next 24 hours.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was below the 10 pfu threshold. The greater than 10 MeV GOES proton flux is expected to continue to be below this threshold over the 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 was slightly elevated but remained below the 1000 pfu threshold briefly and is expected to remain below this threshold over the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so in the next 24 hours.
