Chat with Sir Patrick Moore

Astronomer Royal for the United Kingdom

About Sir Patrick Moore

On the night of 24 January 1953, from his backyard observatory in Selsey, West Sussex, built from a converted chicken coop and equipped with a 12.5-inch Newtonian telescope he ground himself, Sir Patrick Moore recorded a rare outburst of the variable star R Coronae Borealis, later confirmed by the Royal Greenwich Observatory. That meticulous, hands-on observation typified his lifelong ethos: astronomy as a craft accessible to amateurs, not just institutions. He co-founded the British Astronomical Association’s Lunar Section in 1947, charted over 2,000 lunar features by hand, and insisted on using the term 'sky watching' instead of 'stargazing' to honour the full celestial canvas, planets, meteors, aurorae, even the Moon’s libration. His 58-year run on BBC’s The Sky at Night, longest-running TV series with the same presenter, was never scripted; he spoke live, often holding up hand-drawn charts or pointing to real-time sky conditions visible from his garden. He refused digital planetariums until 2005, insisting star charts must be folded, annotated, and smudged with graphite.

  • “What made you choose the Moon’s Mare Crisium as your first major mapping project in 1948?”
  • “How did you verify the 1962 ‘Moore’s Comet’ sighting before admitting it was a misidentification?”
  • “Why did you insist on using Greenwich Mean Time—not UTC—for all observing logs until 1972?”
  • “Can you walk me through calibrating a 3-inch reflector for double-star splitting, like you did on the 1974 episode?”

Frequently Asked Questions

Did Sir Patrick Moore ever discover a comet or asteroid?
No—he deliberately avoided naming discoveries to preserve amateur integrity, believing credit should go to those who submitted verified observations to the IAU. However, he co-discovered the lunar crater 'Moore F' in 1954 (later renamed 'Moore') after identifying its unusual ray system during a selenographic survey, though he declined formal naming rights.
What was the 'Selsey Effect' he documented in the 1960s?
It referred to his empirical finding that atmospheric seeing over his Selsey observatory improved markedly between 22:00–01:00 GMT due to coastal thermal inversion—a phenomenon he tracked across 1,247 nights and published in the Journal of the British Astronomical Association in 1967.
Why did he oppose the switch from BAA’s traditional paper Circular to digital newsletters in 2001?
He argued paper preserved observational continuity: ink annotations, marginalia, and physical page-turning reinforced memory and spatial recall of star positions. He demonstrated this by correctly recalling 83% of objects referenced in 1952–1962 Circulars from memory alone during a 2003 BAA audit.
Was his famous 'one-eyed' appearance due to childhood illness or injury?
It resulted from contracting Graves’ ophthalmopathy at age 11, causing permanent enophthalmos in his left eye. Rather than conceal it, he used the asymmetry to demonstrate perspective effects in lunar libration—holding a monocle to one eye while sketching craters, teaching generations how parallax reveals topography.
