Highlights of Solar and Geomagnetic Activity
03 - 09 March 2008
Solar activity was very low, no flares were observed during the period. Region 984 (S08, L=251, class/area Bxo/030 on 06 March) was numbered on 05 March. The region rotated beyond the west limb on 07 March.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 03 - 08 March.
The geomagnetic field was at mostly quiet levels from 03 - 08 March. Activity levels increased to quiet to minor storm levels midday on 08 March due to a recurrent coronal hole high speed stream that rotated into a geoeffective position. Solar wind speed measurements at the ACE spacecraft began the period at about 600 km/s and declined until late on 07 March when speed reached a minimum of approximately 300 km/s. Solar wind speed began increasing late on
07 March and reached a maximum of approximately 700 km/s at 2023 UTC on 09 March. By the end of the summary period solar wind speed was below 650 km/s
Forecast of Solar and Geomagnetic Activity
12 March - 07 April 2008
Solar activity is expected to be very low.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on all days of the forecast period except 26 March and 05 April.
The geomagnetic field is expected to be at quiet to active levels on 12 - 19 March as the coronal hole high speed stream continues to be geoeffective. On 20 - 24 March expect mostly quiet levels. On 25 - 29 March activity levels should increase to unsettled to major storm levels as the next coronal hole rotate into a geoeffective position. From 30 March through 07 April activity levels should decline to mostly quiet to unsettled levels as effects from the coronal hole
high speed stream subsides.
