Solar Activity Report for 2/14/04
- View Source** Aurora Watch In Effect **
The Earth is still inside of a coronal hole high speed solar wind
stream, and the solar wind speed is over 700 km/sec. An aurora watch
remains in effect. Skywatchers in the higher latitudes should keep an
eye out for aurora. The current conditions are expected to last for
about another 48 hours before settling down. Only two numbered
sunspot regions are visible on the solar disk, and neither appears to
have the potential to generate a significant flare at the present time.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 64
SFI : 104
A index : 17
K index : 4
Solar wind speed : 719.7 km/sec
Solar wind density : 0.6 protons/cc
Solar wind pressure : 0.5 nPa
IMF : 4.7 nT
IMF Orientation : 1.4 nT South
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 continue at very low levels. There is a
small chance for a C-class flare from Region 554.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to active with isolated
minor storm periods at high latitudes. The coronal hole high speed
stream in effect now is expected to continue through 16 February.
Predominantly quiet to unsettled levels with isolated active periods
are expected on 17 February.
