Solar Activity Forecast: Solar activity is expected to be low to moderate with a slight chance for a major event for the next three days (03-05 August). Region 1261 and Region 1263 are both capable of producing a major event and both have a slight chance of producing an energetic proton event.
Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on day one (03 August). Day two is expected to be predominately quiet with chance a for isolated active conditions late in the day. Day three (05 August) is expected to be unsettled to active with a chance for minor storm conditions. The increase in activity is forecast due to the expected arrival of the coronal mass ejection from 02/0616Z. Due to the enhanced environment there is a chance for the 10 MeV protons to cross event thresholds with shock arrival.

Snapped this today using the 400mm lens with baader astro solar filter. On view from L to R are giant sunspots 1263, 1261 and 1260, I could see the first two easily with the protected naked eye. 1216 has produced numerous flares and a CME which is heading towards Earth which will cause aurora displays on the nights ahead. 1263 is massive with X-class flare potential so the sun is a very busy and exciting place at the moment.

Thanks very much Richard, the Canon kit lens has a very bad macro system I have to admit so for these I stepped back a little and zoomed in, then cropped the final result. The Bee then made it back outside to safety so it was a happy ending.
