To ‘third’ these comments, I would say that Jonathan’s greatest achivement over these years had been maintaining the BAA and SPA combined comet webpage in a way that has made it perhaps the most useful and practical port of first call for anyone looking for up to date information on what comets are actually visible with amateur equipment from their particular location. Comets are coming and going all the time, and the fact that this page always seemed to be maintained reliably and was up-to-date with basic information, that could then be followed-up elsewhere, is quite remarkable in view of Jonathan’s work schedule with extended visits to Antarctica. It has always been very useful to someone like me who is not sufficiently interested in comets to subscribe to the specialised newslists, but wants to dip in from time to time.
