Nick Hewitt tells me that Roy Panther (Walgrave, UK) died recently and his funeral was last week.
Roy was the discoverer of comet C/1980 Y2 (1980u). The discovery was made visually using a 0.20m, f/4 Newtonian at 1850 UT on Christmas day 1980 when the comet was a 9th magnitude object near M56. The discovery was confirmed that evening by Mike Hendrie and George Alcock and it was Roy's first success after 601 hours of searching. Martin Mobberley has an interesting Sky at Night on his Youtube channel which includes an interview with Roy.
Roy was the last living British visual comet discoverer. An account of his discovery, as published in the 1981 January edition of TA is attached.
