Multinational LOFAR telescope goes sub-arcsecond

The international LOFAR telescope has for the first time imaged the low-frequency radio sky with stations in four countries (Netherlands, Germany, France, UK). With baselines up to 1000 km, the observations at 120-165 MHz frequency achieved a resolution of 0.3 arcseconds (1/6000 of the size of the Moon). This is not only a new record for LOFAR but for radio astronomy in this frequency range in general.
The first observations of the quasar 3C196 were analysed by Olaf Wucknitz from the Argelander Institute of Astronomy (AIfA) at Bonn University, following up on previous work at 30-80 MHz with stations in only two countries.
