Abstract: | The first observations of solar coronal bright points made at 20-cm wavelength with the VLA are reported. The brightness temperature of the sources observed varies between 1 and 5 x 10 to the 5th K. The observations indicate that significant fluctuations in the brightness temperature as well as in the spatial extent of these sources can occur over a few minutes. These fluctuations are shown to be due to density and temperature fluctuations at transition region heights combined with either plasma motions along magnetic field lines or changes in magnetic field topology, or both. |
