I won't be surprised if we don't see another spotless day this year.

RARE BLUE AURORAS OVER CANADA: A solar wind stream hit Earth during the early hours of July 28th. First contact rattled Earth's magnetic field and sparked rare blue auroras over Canada. Joel Weatherly sends this picture of the colourful spray just outside Edmonton:

Popped in here to check on how the year is going and expected more spotless days.  The cycle must really be ramping up, where is the best place to look at the graphs and predictions ?  I've forgotten where I used to go pre-cycle 24.

I think that although not so many spotless days, the sun isn't all that active. Solar flux has only spent a few days >100...
