Just a quick reminder that The Sky At Night is on BBC Four tomorrow night at 20:00 (more details, repeats etc., here). The title is ‘The Sun revealed’ and looks as if it will be covering the onset of solar cycle 24 and the Ulysses spacecraft which I blogged about recently.

07.04.08 edit: If you are in the UK you can also watch the programme on BBC iPlayer here for the next 6 days.
