In the last 24 hours Solar flare activity reached moderate levels with three M-class flaresduring the period. The largest flare was an M6.4 at 10 to 0648 utc fromnewly numbered Region 3922 which was the mostfrequent flare producer. coronal mass ejection activity was evident in association withthe M6.4 flare but due to the far eastern location, an Earth-directedcomponent is unlikely. The largest and most complex region on thedisk, Region 3917 , was responsible for fourC-Class flares. Region 3921 was numbered but hasbeen inactive. All other regions have been quiet. No Earth-directed coronal mass ejection activity was observed in available LASCO imagery. R1-R2 radio blackouts are likely with a slight chancefor R3 levels 10 to 12 december based primarily on the flare potentialof Regions 3912, 3917, and 3922.
In the last 24 hours The greater than 2 mega electron volt electron flux was at normal to moderate levels. The greater than 10 mega electron volt proton flux remained at background levels. The greater than 2 mega electron volt electron flux is expected to continue at normalto moderate levels. The greater than 10 mega electron volt proton flux is expected toremain at background levels over 10 to 12 december barring any notable flaresthat may cause an increase.
In the last 24 hours Solar wind parameters have been elevated due to the likely arrival of ahigh speed stream associated with two positive polarity coronalholes; coronal hole 97 in the southern hemisphere and coronal hole 98 inthe northern hemisphere. Total field remained around 10 nano tesla for much ofthe period and has recently decreased to 6 nano tesla. The Bz component has beenmostly variable between +6 to to 9 nano tesla. Solar wind speeds averaged around 475 kilometers per second with a max of 583 kilometers per second observed at the ACE satellite. The phiangle has remained in the positive orientation. Solar wind parameters are likely to remain enhanced 10 to 11 december with theongoing HSS with waning conditions 12 december.
In the last 24 hours The geomagnetic field has been at mostly unsettled levels with anisolated active period between the 00 to 03 utc synoptic period due to theHSS associated with positive polarity coronal hole 97 in the southernhemisphere and 98 in the northern hemisphere. The geomagnetic field is expected to continue at unsettled levels, withisolated active periods, as the aforementioned coronal holes remaingeoeffective 10 to 11 december. Waning influences towards quiet levels areexpected 12 december with isolated periods of unsettled as the geomagneticfield relaxes.
