On the subject of that elusive golden orb, Andy Burns and his team from the Herschel Museum of Astronomy were out & about in Bath Abbey precinct inviting passers-by to enjoy a bit of solstice sun-gazing. Did you know the sun has an eleven year cycle of building up magnesium activity which is then released as a vast plasmic sun-spot? Nor me. Sadly, and unsurprisingly really, this is the quietest the sun has been for about 130 years so no sunspots today.
