** Aurora Watch In Effect **
The Earth has begun moving into the high speed solar wind stream
coming from a coronal hole, and about a day earlier than expected.
The solar wind speed is on the high side of 600 km/sec, and G-1
geomagnetic storm conditions have been observed within the last 24
hours. As a result, an aurora watch is now in effect. The current
conditions are expected to last about another 48 hours or so before
things calm down a bit. The background X-ray flux has risen rather
quickly, indicating that we may be in for a bit of flare activity.
Sunspot regions 424 and 431 could produce an M-class flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 114
SFI : 123
A index : 25
K index : 4
Solar wind speed : 620.8 km/sec
Solar wind density : 2.3 protons/cc
Solar wind pressure : 1.6 nPa
IMF : 4.7 nT
IMF Orientation : 1.2 nT North
Conditions for the last 24 hours :
Space weather for the past 24 hours has been minor. Geomagnetic storms
reaching the G1 level occurred.
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 at low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be at unsettled to minor storm
levels through day one of the forecast period due to a recurrent high
speed coronal hole stream. A decrease to predominantly unsettled with
isolated active conditions are possible by day two as the coronal hole
