Solar Activity Report for 6/9/05
- The Earth has exited the high speed solar wind stream mentioned in my
last report, and the overall activity level has dropped off
accordingly. There is, however, the potential for some interesting
events. There are currently four numbered sunspot regions visible.
Two of them, regions 775 and 776, have been growing both in size and
in magnetic complexity. Both have the potential to produce an M-class
flare, and both are in an Earth-pointing position. Stay tuned to see
if either of these two sunspot regions does anything noteworthy.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 99
SFI : 116
A index : 3
K index : 1
Solar wind speed : 354.7 km/sec
Solar wind density : 1.2 protons/cc
Solar wind pressure : 0.2 nPa
IMF : 3.2 nT
IMF Orientation : 2.4 nT North
GOES-12 Background X-ray Flux Level : B2
Conditions for the last 24 hours :
No space weather storms were observed for the past 24 hours.
Forecast for the next 24 hours :
No space weather storms are expected for the next 24 hours.
Solar activity forecast :
Solar a activity is expected to be at low levels. Regions 775 and 776
may both be capable of producing an isolated low level M-class flare.
Geomagmetic activity forecast :
The geomagnetic field is expected to be at predominantly quiet to
unsettled levels. Beginning late on 11 June, active conditions may
occur due to the arrival of the faint partial halo CME that was
