Aurora over South of England

Amazing aurora over Selsey Observatory midnight on 10th May 2024. We are nearly at the peak of a sunspot cycle so watch out for more events.

Lecture to Chichester AS (South Downs) lots of questions.

The lecture on technical challenges of measurement in astronomy went well and loads of interesting questions. All started from the slow (15years) of looking for exoplanets round V470 Cam. Easily visible reduction in the errors over the time I have been making measurements. Some of the error reduction techniques I have used.

New Lecture on ‘Time’ went well.

Delivered to a great audience at the Farnborough Site (Cody AS). Mix of history, science, technical information and current research. Need to put it on Astrospeakers.org
