Solar Activity Report for 4/07/05
- The Earth is emerging from a high-speed solar wind stream coming from
a coronal hole. This one actually managed to touch off some activity,
and aurora were spotted in the high latitudes of Canada and Alaska, as
can be seen here.
It's been awhile since we've seen any aurora! There are three sunspot
regions visible at thr present time, although none appear to have the
potential for producing a significant flare. However, there is yet
another coronal hole that is rotating into an Earth-pointing position,
and we should start seeing the solar wind speed pick back up along
about the 8th.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 49
SFI : 88
A index : 9
K index : 1
Solar wind speed : 386.1 km/sec
Solar wind density : 1.8 protons/cc
Solar wind pressure : 0.4 nPa
IMF : 3.0 nT
IMF Orientation : 1.2 nT South
GOES-12 Background X-ray Flux level : A6
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 very low to low.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled on 08 and
09 April. On 10 April, quiet to active conditions are expected due to
the effects of a recurrent coronal hole high speed stream.
Recent significant solar flare activity :
