Highlights of Solar and Geomagnetic Activity
08 - 14 March 2010
Solar activity was at very low levels during 08 - 11 March with isolated to occasional B-class flares. Activity increased to low levels during 12 - 14 March due to isolated low-level C-class flares from Region 1054 (N15, L=149, class/area Eai/240 on 15 March). One of these flares, a long-duration C1/Sf at 13/2349 UTC, was associated with a slow, Earth-directed partial-halo CME (estimated plane-of-sky velocity around 360 km/sec, based on SOHO/LASCO
images).
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during 08 - 10 March. Fluxes increased to moderate levels on 11 March. A further increase to high levels occurred during 12 - 14 March in response to a coronal hole high-speed stream.
Geomagnetic field activity was at quiet levels at all latitudes during 08 - 09 March. Field activity increased to quiet to unsettled levels during 10 - 11 March with brief active to minor periods at high latitudes. Activity increased to quiet to active levels on 12 March with a brief period of minor storm at high latitudes. Activity decreased to mostly quiet levels during 13 - 14 March. ACE in situ solar wind measurements indicated a coronal hole high-speed stream (CH HSS) occurred during 10 - 13 March. The CH HSS peak velocity was 577 km/sec at 12/0601 UTC. Interplanetary Magnetic Field changes during the CH HSS included increased Bt (peak 9 nT at 10/1521 UTC) and periods of sustained southward Bz (minimum -7 nT at 10/1515
UTC).
Forecast of Solar and Geomagnetic Activity
17 March - 12 April 2010
Solar activity is expected to be very low with possible isolated periods of low levels during the forecast period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels through most of the period. However, moderate to high flux levels are possible during 08 - 11 April.
Geomagnetic field activity is expected to be at quiet to unsettled levels during 17 - 18 March due to weak CME effects. Quiet conditions are expected during 19 March - 06 April. Activity is expected to increase to quiet to active levels during 07 - 08 April due to a recurrent coronal hole high-speed stream. Activity is expected to decrease to quiet levels during 09 - 12 April.
