Its not too often you see sunspot number of zero, but that's what we
have now. Not a single sunspot visible! As a consequence, the solar
flux index is also unusually low. That does not, however, mean that
there cant't be activity, and even aurora! The Earth is now passing
through a high-speed solar wind stream coming from a coronal hole.
Actually, the solar wind speed is only in the 400's, but given the
time of year, that might be enough to cause aurora displays in the

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.
Geomagnetic activity forecast :
The geomagnetic field is expected to be quiet to unsettled, with
isolated active conditions possible all three days from the effects of
a recurrent high speed solar wind stream.
