The Earth has crossed into a high-speed solar wind stream coming from
a coronal hole. At the initial boundary crossing, G-1 geomagnetic
storm conditions were noted. Even though summer is not a good time
for aurora, aurora were seen and photographed in Canada. This is the
first time we've seen aurora in quite awhile. Here's the obligatory
picture, taken in Quebec.
As of right now, the Earth is in the process of exiting the solar
wind stream, so any more aurora sightings are unlikely. Expect the
solar wind speed to slow down over the coming days. There are two
small sunspot regions visible. At the present time, neither one
appears to be capable of generating a signigicant flare.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 26
SFI : 81
A index : 19
K index : 3
Solar wind speed : 486.0 km/sec
Solar wind density : 2.5 protons/cc
Solar wind pressure : 1.0 nPa
IMF : 4.3 nT
IMF Orientation : 3.7 nT North
GOES-12 Background X-ray Flux level : A3
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 remain at very low levels.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled. Isolated
active periods are possible on 02 - 03 July as the high speed coronal
hole stream subsides.
Recent significant solar flare activity :
