Sunspot group #11035 released yet another C class solar flare, this time a 
C7.6 at 1855 UTC. This solar flare is now the largest so far for solar cycle 
24. Looking at the latest Lasco 2 and 3 imagery it appears that a 
geoeffective (Earth directed) coronal mass ejection (CME) was released. The 
CME could trigger geomagnetic storming here on Earth several days from now.

Tentatively we have a new sunspot group that has just risen above the 
eastern horizon of the Sun. If so and it survives it will be numbered 11036. 
However we will need another day to really get a good look at it. Yesterday 
it released a very small B9.7 solar flare and non geoeffective (Earth 
directed) coronal mass ejection (CME).

The solar flux index is 88, a new solar cycle 24 high and the sunspot number 
is 24.
