Abstract: Solar flares are among main extraterrestrial events that are well known to severely affect both space weather and near-Earth surrounding conditions. Under incident X-ray solar flare radiation, ionospheric plasma undergoes perturbations clearly and distinctly observable on ground-based monitoring systems' recordings. Mid-latitude lower ionosphere under influence of energetic solar flare events was examined by employing different numerical modeling procedures, including Machine Learning, relying on ground-based Very Low Frequency (VLF) radio signal recordings from Belgrade VLF database and solar soft X-ray irradiance satellite measurements taken from Geostationary Operational Environmental Satellite (GOES) database.
