Abstract
Using Irkutsk digisonde data obtained in 2003-2011, a morphological analysis of the G condition occurrence has been made. The G condition was found to occur during daylight hours in summer; in winter, it is extremely rare, and its appearance is associated with intense magnetic storms. In the years of moderate solar activity, the G condition is most frequently registered at Kp ⩾ 4, in the forenoon. During low solar activity, it can be observed under quiet geomagnetic conditions; in most cases, local time of its appearance shifts to afternoon hours. The highest percentage of the G condition occurrence (7.7-6.4%) was recorded in June and July 2008 when the levels of solar and geomagnetic activity were abnormally low.
