Abstract

From April to June of 2019, the solar hydrogen spectral line was observed with the three-meter Baghdad University Radio Telescope (BURT) using the raster scan mapping technique. This technique allowed for the production of solar intensity contour maps and its surrounding region, which emitted at the wavelength of 21 cm. The contour maps estimated by employing square windows in the sky of various sizes that involved the Sun and its surrounding area. These maps were represented in terms of solar received power, antenna temperature, and brightness temperature. The maximum values of the received power, antenna temperature and brightness temperature were obtained using an 8°×8° window of size, found to be -46 dBm, 288 K and 2300 K respectively. To investigate our results, the root mean square noise in a total power measurement was calculated for each selected window. The findings revealed that the smallest errors occurred with larger window sizes, and found to be 1×10-3 at window size of (8°×8°) and this gives a good indication about results accuracy. All these results showed in a good agreement with solar observations at the wavelength of 21 cm using a small radio telescope.
