| Description: | This amusing picture is just a teaser for the real thing, which we had some trouble in showing directly. For a wonderful movie of the radio sky above LOFAR, click on the following link: http://www.youtube.com/watch?v=7uRka5jXbNM An all-sky movie of the radio sky above the LOFAR prototype near Exloo, The Netherlands, at a frequency of 50 MHz. The data were taken at 29 and 30 April 2008. The edge of the circle is the horizon. North is up, East towards the left. The movie shows Cas A and Cyg A twinkling (scintillating) like stars, as well as the Galactic centre rising and setting. Near the end of the movie, there are thunderstorms over Germany visible towards the east. The total duration of the observation was 24 hours. |
