Abstract
The effects of a geomagnetic storm on 5 April 2010 on electric parameters of the atmospheric near-ground layer in Kamchatka have been investigated. Three processes over the course of the storm were identified. Air electroconductivity began to decrease 4 h before the storm, and this lasted for 20 h. The storm's sudden commencement caused potential gradient oscillations with amplitudes up to 300 V/m. During the stages of the storm, a significant increase in the atmosphere ion content unipolarity coefficient occurred.

Measurements of potential gradient (PG) were realized by the ‘Pole-2’ sensor, which was developed at a branch of the Voeikov Main Geophysical Observatory (Imyanitov 1957)
After digitization by a 14-bit analog-to-digital converter (ADC), the signal at the output of this fluxmeter was recorded on a personal computer (PC) hard disc with a 1-s sampling rate
