Sun Jun 16 09:32:29 EST 2013

A large sunspot group (AR 1768) is located in a fairly geo-effective
position on the south west quadrant of the Sun and a new group of
sunspots (AR 1769 to 1772) has appeared on the south east quadrant.
This new group is increasing the solar EUV flux absorbed in the
Earth’s ionosphere. A minor C class flare occurred at 04 UT on June 15
and solar flare activity is expected to remain low to very low (B and
C class flares) during the next 24 hours. Elevated solar activity is
possible later this week and geomagnetic conditions are expected to
become unsettled when faster solar wind arrives during the next 2 to 3
days. Geomagnetic conditions will remain at quiet levels today and
high-frequency radio communication will remain close to monthly
predicted conditions.
