Bulletin

The solar flaring activity over the past 24 hours remained at low levels. There are eight active regions on the visible solar disk and ongoing flux emergence mainly in the northern hemisphere. Most of the flaring activity was produced by the active region which rotated from behind the north-east limb yesterday and is now numbered as NOAA 3141 (beta). A neighbouring region NOAA 3140 (alpha) was numbered, but did not produce any significant flaring activity. An isolated low C-class flaring was also produced by a new unnumbered active region near N24E02. Regions NOAA 3131 (alpha), NOAA 3135 (beta), NOAA 3136 (alpha) and NOAA 3139 (beta) have shrunk in area and lost some trailing spots. Region NOAA 3137 (beta) has shown some further development, but remained inactive. The flaring activity over the next 24 hours is expected to be at low levels with low chances for isolated M-class flaring.

No Earth-directed coronal mass ejections CMEs were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been mostly above the1000 pfu threshold over the past 24 hours and is expected to remain so over the next 24 hours. The 24h electron fluence was at moderate levels and might reach high levels over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) remained under the influence of a high speed stream (HSS). The solar wind velocity was in the range of 410 km/s to 617 km/s. The interplanetary magnetic field declined towards a maximum value of 6.4 nT with a minimum Bz component of -5.1 nT. The magnetic field remained predominantly in the positive sector (directed away from the Sun). The solar wind velocity and temperature are expected to remain enhanced under the declining influence of the HSS on Nov 5th and Nov 6th. A small and narrow positive polarity coronal hole currently resides on the central meridian and could bring some enhanced solar wind conditions late on Nov 7th and Nov 8th.

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Quiet to unsettled geomagnetic conditions are expected for the next 24 hours with chances for isolated active periods.

Today's estimated international sunspot number (ISN): 099, based on 10 stations.
