Scientific paper

A looplike structure connecting two sunspots of opposite polarity in an active region has been observed at 6 cm with a resolution of 3.5 arcsec, using the Very Large Array. This loop structure is reminiscent of the X-ray loops, as observed, for example, from Skylab. The brightness temperature in the 'loop' is one-million K and five-million K near its foot points. Most of the bright peaks in the 'loop' are well aligned with a long neutral line. Several compact, highly circularly polarized emission peaks were observed over emerging flux regions near one of the spots. Some of these sources appear to be associated with arch filament systems. The low brightness emission in the 'loop' is attributed to optically thin thermal bremsstrahlung.
