VLF SIGNAL VARIATIONS SEEN IN THE BUCHAREST OBSERVATORY RECORDINGS.

This paper presents a new instrument setup at the Bucharest Observatory of the Astronomical Institute of the Romanian Academy, as well as preliminary results using this setup. It consists of records of VLF (very low frequency) perturbations using a superSID instrument. During March and December 2022 various mounts and settings tests have been performed. Starting October we obtained satisfactory data. We report on detecting the signature of moderate to intense solar flares (M and X-class). In this configuration, the C-class solar flares are less distinguishable from the background noise. [ABSTRACT FROM AUTHOR]
