Abstract This work presents the first simultaneous X‐ray measurement and high‐speed video observation of propagation a lightning leader producing X‐rays. As result, three‐dimensional distance from and, for time, conditions preexisting channel during were observed. Although four leaders in this seven‐stroke flash followed same path to ground, X‐rays only observed before return stroke with highest peak current. The fact that other three following ground did not produce detectable confirms...
Abstract High‐energetic charged particles, such as solar protons, and phenomena Forbush decreases are eligible candidates to affect the global electric circuit. These effects have been studied by analyzing disturbances of potential gradient in ground‐based measurements fair weather regions. In this paper, we investigate deviations diurnal curve, during proton events, decreases, from mean values obtained conditions. each situation, select only events which not accompanied or followed other....
Abstract The Large Aperture GRBs Observatory is a continental-wide observatory devised to detect high energy (around 100 GeV) component of Gamma Ray Bursts (GRBs), by using the single particle technique in arrays Water Cherenkov Detectors (WCDs) at mountain sites Argentina, Bolivia, Colombia, Guatemala, Mexico, Venezuela and Peru. Details instalation operation detectors Marcapomacocha Peru 4550 m.a.s.l. are given. detector calibration method will also be shown.
