Leszek Blaszkiewicz - Ionospheric scintillation monitoring with Bałdy LOFAR station - October 29, 2018 • 490 Views
The phenomenon of the ionospheric scintillation is well known and has been studied for years. GNSS techniques used widely in ionospheric studies plays also significant role in this area. Modern instruments like Low Frequency Array (LOFAR) telescope creates a great opportunity for further and deeper study of the phenomenon. International LOFAR Telescope (ILT) single station is able to obtain dynamical spectra with temporal resolution of 1 second and typical frequency resolution 0.1953 MHz in 8-bit mode. During this kind of observations telescope is able to cover bandwidth from 10 up to 240 MHz (it is corresponding to wavelengths of 30-1.2 m). Using the ILT station in Bałdy called PL612, regular observations of dynamical spectra are made. We focus on two very bright radio sources: Cas A and Cyg A, whose signal allows the analysis of scintillation from the ionosphere and search for correlations with results obtained by other methods (GNSS techniques mainly). The detailed description of methods of observations as well as data analysis and some examples of observations of scintillations recorded will be presented.
