“…It should be noted that in accordance with the geographic location of the GICs registration chain and Faraday's law of induction, increase of the GICs at VKH and KND stations will be mainly driven by rapid change in the Y-component of the magnetic field, while at the MAN station in the X-component (Setsko et al, 2023). It was shown that the strongest GIC (~42A) during first interval, observed at ~20:45 UT on 23 April.2023, was related to the appearance of a new substorm intensification caused by the rotation of the IMF BZ to the north (Figures 4 and 5).…”

“…The strongest GIC (-42 A) was observed at VKH at ~20:43 UT, when there were large negative (~ -1500 nT) and positive (~750 nT) bays in the X-and Y-components in LOZ, respectively (Figure 4c). Note that, due to location of the Karelian-Kola power line and by Faraday's law of induction, increase of the GIC at VKH and KND stations will be mainly driven by rapid change in the Y-component of the magnetic field (Setsko et al, 2023). As seen from Figures 4a and 4b, these strong magnetic disturbances were associated with the appearance of a new substorm during the recovery phase of the previous substorm.…”

“…(Oliveira et al, 2017;Vorobjev et al, 2018;Apatenkov et al, 2019;Kozyreva et al, 2020;Lakhina et al, 2020;Yagova et al, 2021;Sakharov et al, 2022). Recently it has been established that the main sources of GIC growth at auroral zone latitudes are the intensification and poleward movement of the westward electrojet current during substorm expansion phases (Despirak et al, 2022 and as well as Pc5 pulsations, usually observed during the recovery phase of substorms (Setsko et al, 2023).…”

We analyzed intense geomagnetically induced currents (GICs) recorded during a complex space weather event observed on 23-24 April 2023. Two geomagnetic storms characterized by SYM-H intensities of -179 nT and -233 nT was caused by southward IMF Bz of -25 nT in the sheath fields and -33 nT in the magnetic cloud (MC) fields. GIC observations were divided into two local time sectors: nighttime (1700-2400 UT on 23 April) GICs observed during the interplanetary sheath magnetic storm, and morning sector (0200-0700 UT on 24 April) GICs observed during the MC magnetic storm. By using the direct measurements of GIC on several substations of Karelian-Kola power line (located in the north-west portion of Russia) and gas pipeline station near Mäntsälä (south of Finland), we managed to trace the meridional profile of GIC increase at different latitudes. It was shown that the night sector GIC intensification (~18-42 A) occurred in accordance with poleward expansion of the westward electrojet during substorm.On the other hand, the intense morning sector GICs (~12-46 A) were caused by Ps6 magnetic pulsations. In addition to the Ps6 pulsations, comparable in intensity morning GIC (~44 A) was associated with a local substorm-like disturbance caused by a high density solar wind structure, possibly a coronal loop portion of an ICME.

“…GICs increase at different latitudes corresponds to the poleward movement on the westward electrojet. The source of the GICs during the third period was short pulses of Pс5 pulsations at the recovery phase of an intense second substorm [see more Setsko et al, 2023].…”
