Can we detect X/M/C-class solar flares from global navigation satellite system data?

Based on the total electron content (TEC) data from global navigation satellite system (GNSS), we analyzed 224 classified solar flares (SFs) occurred in 2014–2017. We suggest an algorithm for SF automatic detection. The algorithm is based on analysis of GNSS-TEC variation derivative averaged over al...
