5th Aug, Sunspots increase
5th Aug.
Last month July saw the mean sunspot number increase to 196.5 - the highest so far for cycle 25. This could mean we are still heading for maximum.
Attached are two images taken this month. Both are single exposures with a canon 550d camera attached to a 81 mm WO refractor with a Herschel wedge at 540 nm. Thanks for viewing.
