Robin, That’s a wonderful description of a very rare observation made by Chris from somewhere called Chelmsford. This is the JBAA report referenced in the S&T article.
though I did not see the Apollo 8 event I do vividly recall seeing the Apollo 12 event from a bedroom window.. This had been a predicted naked eye event. I dare say many others saw it also.
Incidentally, the same window from which I had my first telescopic view of the plant Mercury
I was one of the first outsiders to see Moon rock and dust samples in Nov 1969 bought back by Apollo 11, at Queen Mary University of London Chemistry department, who were given small samples for analysis.
