That is really sad news. I met Bob at the TA AGM in 2006 September. At that meeting we had Tom Boles, Mark Armstrong, Maurice Gavin and Ron Arbour, all of whom had discovered supernovae using imaging. By that time Bob had discovered around 40 supernovae, all visually. Bob’s talk was excellent and should be around on video somewhere. I do remember him passing on greetings to those of us who lived “in the northern polar regions”. I don’t think he fancied observing from here!
