** Aurora Watch In Effect **
The Earth is inside of a high-speed solar wind stream coming from a
coronal hole. Even though the solar wind speed isn't that high, G-1
geomagnetic storm condition have been observed within the last 24
hours, and an aurora watch is in effect. The most likely place to
spot aurora will be in the higher latitudes. The current conditions
are expected to last for another 48 hours before settling down. There
are still six numbered sunspot regions visible, but none of them
appear to have the capability of generating a significant flare. Of
the group, regions 606, 609, and 612 will be rotating out of view by
the end of the weekend.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 109
SFI : 105
A index : 16
K index : 3
Solar wind speed : 547.7 km/sec
Solar wind density : 4.8 protons/cc
Solar wind pressure : 1.9 nPa
IMF : 6.2 nT
IMF Orientation : 2.6 nT North
Current GOES-8 background X-Ray flux level : B2
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 low. Most of the activity is expected
to occur in Region 618.
Geomagnetic activity forecast :
The geomagnetic field is expected to be mostly unsettled but with a
fair chance for some isolated active periods during the next two days
(21-22 May). A decline to quiet to unsettled is expected around
mid-day on the third day (23 May).
