Highlights of Solar and Geomagnetic Activity
07 - 13 September 2009
Solar activity was very low. A single low-level B flare occurred on 08 September. The visible disk was spotless.
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 quiet levels during the period. Solar wind velocities at ACE ranged from 279 to 372 km/s. Interplanetary magnetic field activity showed intermittent periods of southward Bz from approximately 11/0557 UTC through the end of the period. Density reached a maximum of 10 p/cc at 13/1605 UTC.
Forecast of Solar and Geomagnetic Activity
16 September - 12 October 2009
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 be at normal levels during the period.
Geomagnetic field activity is expected to be at quiet to unsettled levels, with isolated active periods during 16 - 17 September due to a recurrent coronal hole high-speed stream (CH HSS). Predominantly quiet levels are expected during 18 - 25 September. Conditions quiet to unsettled conditions, with isolated active levels are expected on 26 September due to a recurrent CH HSS. Activity will decrease to predominantly quiet levels during 27 September - 11 October. Quiet
levels, with isolated unsettled periods, are expected on 12 October, due to a recurrent CH HSS.

Two new sunspot groups ?
Posted at www.wcflunatall.com/nz4o1.htm
and www.wcflunatall.com/nz4o4.htm
There are two very small sunspots trying to emerge in the SW quadrant of the sun. We can only hope against hope that they emerge and get assigned numbers 11026 and 11027.
