No – not the content of the release, that’s still embargoed, but how you can watch the press conference yourself…
This is what I’ve been told are the arrangements for Planck Day, Thursday 21 March:
There is an ESA Press Conference in Paris from 9am UK time, with talks from the ESA Director General and George Efstathiou. There will be a simultaneous press event at the RAS here in London which will stream the Paris talks, and will be followed by a panel discussion and Q&A featuring Andrew Jaffe (Imperial), Mark Ashdown (Cambrdige), Richard Battye (Manchester), Anthony Challinor (Cambridge), Jo Dunkley (Oxford), Steve Gratton (Cambridge), Paul Shellard (Cambridge) and Locke Spencer (Cardiff).
There will also be an afternoon session in Paris with more technical talks.
Both morning and afternoon Paris talks will all be streamed at http://www.esa.int.
Papers will be up on the ESA site at about noon Thursday, and on astro-ph Friday morning.
