In an article for the Guardian Science Blog, LOFAR-UK member Dr. Alan Penny from the University of St. Andrews, argues that we should think more about what to say to aliens if we ever do detect them.
"We Need to Talk about Aliens"
Alan is leading efforts to run test SETI observations using the LOFAR-UK station in stand-alone mode (ie. not connected to the rest of the LOFAR array).

Test observations at Chilbolton
Observations to test the system are ongoing at Chilbolton, both when the station is linked to the full LOFAR array and controlled from ASTRON, but also with it running in its "standalone" mode, (ie. controlled locally, and using it as a single telescope).
At the end of last week observations were run in standalone mode to test some new parameters. The lastest tests involved pointing at three different places in the sky at once (using the multi-beam capacity - since LOFAR stations are pointed entirely in software, by adding three sets of different delays in the antennas can be used to point 3 places at once), and also testing if data could be taken at 1 Hz frequency resolution across a full band 36 MHz wide.
This kind of data will be useful for all sorts of observations in single station mode, but in particular this observations was used as a dry run for SETI observations as part of Project Dorothy.
The aims of Project Dorothy (for a nice description of the goals and some quotes from Frank Drake here) are to co-ordinate world-wide observations of nearby stars with planetary systems to search for signals of possible extra-terrestrial origin.
In practice the observations last week were no different from any other kind of commissioning (or test) observations which have been run at Chilbolton, except that the time and targets were set to co-ordinate with Project Dorothy at the request of the LOFAR-UK SETI group.

SETI on TV
One of our plans for the LOFAR-UK station is to perform some SETI (Search for Extraterrestrial Intelligence) experiments (hopefully some as part of the remaining Project Dorothy dates). You'll hear more about this in the future.
This is just a quick post to point out that this week on the BBC there was a program about the Drake Equation (still available on iPlayer: http://www.bbc.co.uk/iplayer/

LOFAR hits the tabloids
An article about SETI with LOFAR appeared in The Sun on Wednesday: "New Scope to Listen for Aliens".
