Abstract

I give an update on my recent activities with LOFAR focused on international baselines. This includes sub-arcsec resolution imaging of several sources in the high band range. In addition there will be comments on solar imaging, using long baselines to calibrate short ones (producing an image of the crab nebula), polarisation of the crab pulsar and about the detection of wide-band RFI from airplanes.

Additional information is available here.
