2741 looks to be a big one then? :)

Thanks for showing us the superb Cak images of the Two Sunspots - . Actually I tried to send but failed to send this response yesterday but failed miserably?
As far as I'm concerned the Sun has bee a revelation recently, since the first fine Sunspot appeared ago. At one stage some SPA members including David Frydman & Alan Heath, actually observed it "unaided" eye. So I ha d been wondering if that Sunspot would manage to complete a full circuit & reappear after half the Sun's rotation periodic or perhaps I should say synodic period - BINGO it DID !
Thank goodness the Sun seems alive & well & hasn't entered the Merrydeath cycle.
Best of luck from Cliff
