I’m sorry to say that the 2021 Solar Data Card included with the December Bulletin contained a number of inaccuracies, all due to an oversight by me and in no way reflecting on the accuracy of the information kindly provided by Fiona Vincent. Apologies to her and to members for the mistake. A corrected version will be included with the March Bulletin and is provided here as a PDF which can be printed on a single sheet of A4 and folded to provide a two-sided A5 “card”.
