Geomagnetic activity during St. Patrick's Day storm inferred from global and local indicators

Abstract: In this research, the comparison between the results of geomagnetic activity monitoring using the new local indicators of geomagnetic activity and the traditional geomagnetic indices for geomagnetic activity analysis is made for the period of the strongest geomagnetic disturbance of the current solar cycle -the St. Patrick's Day storm (17-18 March 2015).The results of the research demonstrated that the classification of magnetic activity using the mentioned indicators does not contradict the classical methods.… Show more

“…The analyzed storms are listed in Table 1. These storms are not the strongest in the mentioned cycles, as we did not analyze some of the most extreme and well-studied events, such as the storm on 20-24 November 2003, or the St. Patrick's Day storm on 17-18 March 2015 [21] that appeared to be the most intense geomagnetic storm in the 24th cycle (Dst index ≤ −230 nT).…”

“…Last visited: 12.03.2018); a similar accident occurred after the storm driven by the X9.0-class solar flare in 2006. Nowadays, thorough and multifactor space weather monitoring is required to prevent the damages from the destructive space weather impact on the technological systems on the Earth [Gvishiani et al, 2016a[Gvishiani et al, , 2016b. To take into consideration these geomagnetic storm aspects, the remainder of the paper is organized as follows.…”
