Left panel: LOFAR 1000″ × 1000″ image of the field around β Gem. Right panel: a zoomed in 300″ × 300″ version of the image shown in the left panel. The restoring beam FWHM is displayed in red in the lower left corner of both images and has dimensions 7.5″ × 3.8″. Contours are set to (−3, 3, 6, 9, 12, 15, 100, 200, 300) × σrms, where σrms = 330 μ Jy beam−1 and is the rms noise at the target position. The red crosshairs mark the expected position of β Gem at the epoch of observation.
