Comparison of a the SYM-H and AE indices with 1 min resolution and ROTI perturbations with 15 min resolution as a function of geographic latitude and time, evaluated along b 85W in North America, c 20E in Europe, d 70W in South America and e 150E in the Australian sector during June 20 and June 22–23, 2015. The left vertical axis for b–e graphs shows geographic latitudes, right axis—the corresponding corrected geomagnetic latitudes
