Highlights of Solar and Geomagnetic Activity
02 - 08 March 2009
Solar activity was very low. No flares were observed. Old-cycle-polarity Region 1014 (S01, L=035, class/area Bxo/020 on 07 March) formed on the solar disk on 06 March. It gradually decayed to a spotless plage region on 08 March.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels during the period.
Geomagnetic field activity was at mostly quiet levels during 02 - 07 March. A weak sudden impulse occurred at 0602 UTC on 03 March in response to a discontinuity in the solar wind observed at ACE at 0451 UTC. ACE solar wind velocities increased from 314 km/s at
03/0450 UTC to 413 km/s at 03/1559 UTC. During this period, interplanetary magnetic field Bz values varied from -5 nT at 03/0627 UTC to 9 nT at 03/1229 UTC. Solar wind velocities at ACE decreased to an average of 370 km/s at 03/1928 UTC and continued through
07/0358 UTC. On 08 March, geomagnetic field activity increased to quiet to unsettled levels, with minor to major storm periods at high latitudes, due to a recurrent enhancement in solar wind speed and the interplanetary magnetic field. During this period, solar wind velocities at ACE increased from 301 km/s at 07/2239 UTC to 457 km/s at 08/1855 UTC.
Forecast of Solar and Geomagnetic Activity
11 March - 06 April 2009
Solar activity is expected to be at very low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to increase to high levels during 14 - 18 March. Normal flux levels are expected during the rest of the period.
Geomagnetic field activity is expected to be at predominantly quiet levels through 12 March. Activity is expected to increase to quiet to active levels during 13 - 14 March with a chance for minor to major storm periods at high latitudes due to a recurrent coronal hole high speed stream. Mostly quiet activity is expected for the rest of the period.
