Solar Activity Report for 2/16/05
- There are a total of five numbered sunspot regions visible, one of
them naked-eye visible. However, none of them have the potential for
producing any significant flares. The only thing that migght break
the current monotony is a coronal hole that has rotated into an
Earth-pointing position. We should begin to see high-speed solar wind
gusts from it along about the 18th. The coronal hole, however, is
relatively small, so don't expect to see anything major out of the event.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 69
SFI : 122
A index : 3
K index : 2
Solar wind speed : 422.1 km/sec
Solar wind density : 1.9 protons/cc
Solar wind pressure : 0.6 nPa
IMF : 5.8 nT
IMF Orientation : 2.9 nT North
GOES-12 Background X-ray Flux level : B1
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 activity is expected to be low for the next three days.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled for
tomorrow (February 16). Mostly unsettled conditions are expected on
February 17 and unsettled to slightly active conditions are expected
on February 18. The increase is anticipated in response to a favorably
positioned coronal hole.
