THE DICKSON ISLAND AND CAPE CHELYUSKIN Q-INDICES OF MAGNETIC ACTIVITY
During the IGY, vertical ionospheric soundings, radiowave absorption studies and auroral radio reflection studies were conducted at 15-minute intervals. For comparison of the ionospheric parameters and auroral data with magnetic activity, the quarter-hourly Q-index was introduced into the routine of...
