Viewed sunspot 1711 with the UofT ToV glasses and then my welders glass. Very satisfying in the latter. Just below the mid-point. Almost centred.
David had asked about it on the RASC Toronto Centre Yahoo!Group. When I checked Spaceweather and saw how large it was, I surmised it would be visible unmagnified.
