LOw Frequency ARray (LOFAR) is an international radio-interferometer operating on a frequency range between 10 – 240 MHz. LOFAR consists of 52 separate stations which work together to form a network of the International LOFAR Telescope (ILT). However, each station can be used in a single mode as well. When working in a single mode, The PL610 LOFAR station in Borowiec, Poland, is used for observations of ionospheric plasma. The used frequency range of the LBA antennas (10-90 MHz) allows studies on weak ionospheric scintillation occurring in a middle geomagnetic latitude region. This phenomenon has not previously been detected in this region by GNSS and can provide valuable information about the local ionospheric conditions. The spectral index is an important parameter allowing description of scintillation, as well as its formation. In the following work, we present the results of the computation and analysis of the automatically computed scintillation spectra. The developed pipeline not only allows the calculation of scintillation spectral index, but also the computation of noise level, Fresnel Frequency, and scintillation power.
