Optical and VLF radio observations of sprites over a frontal storm viewed from O’Brien Observatory of the University of Minnesota
Autor: John R. Winckler
Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 60:679-688
Video images, and photometric and VLF data, were obtained by the University of Minnesota SKYFLASH system of 38 ‘sprite’ events associated with a strong frontal system located in the upper midwest, U.S.A., on 20–21 June 1996. Besides two image-i

The cloud–ionosphere discharge: A newly observed thunderstorm phenomenon
Autor: John R. Winckler
Publikováno v: Proceedings of the National Academy of Sciences. 94:10512-10519
This paper deals with a luminous electric discharge that forms in the mesospheric region between thundercloud tops and the ionosphere at 90-km altitude. These cloud–ionosphere discharges (CIs), following visual reports dating back to the 19th centu

Autor: R. J. Nemzek, T. E. Nelson, W. A. Lyons, John R. Winckler
Publikováno v: Journal of Geophysical Research: Atmospheres. 101:6997-7004
New observations of sprites (cloud-ionosphere luminous discharges above thunderstorms) were made from the Yucca Ridge Field Station 20 km northeast of Fort Collins, Colorado, on the night of July 11–12, 1994, as part of a summer 1994 observing camp

Autor: R. J. Nemzek, R. C. Franz, John R. Winckler
Publikováno v: Journal of Geophysical Research: Atmospheres. 98:8775-8783
This paper presents further discussion of and new data on fast subvisual increases in the luminosity of the night sky described in our previous papers. A detailed technical description of the simple telescopic photometers used in the project SKYFLASH

Controlled experiments in the earth's magnetosphere with artifical electron beams
Autor: John R. Winckler
Publikováno v: Reviews of Modern Physics. 64:859-871
This article describes the Electron Echo project, which used artificial electron beams to determine how natural particles are accelerated and lost from the trapping region in the earth's magnetosphere. The problems of injecting electron beams into th

Electron beam sounding rocket experiments for probing the distant magnetosphere
Autor: R. J. Nemzek, John R. Winckler
Publikováno v: Physical review letters. 67(8)
Electron accelerators on sounding rockets have injected 8-40-keV electrons on closed magnetospheric tail field lines near 250 km altitude in the northern auroral zone. These beams mirrored at the southern conjugate point ad returned as 'echoes' which

Further observations of cloud-ionosphere electrical discharges above thunderstorms
Autor: John R. Winckler
Publikováno v: Journal of Geophysical Research. 100:14335
During the night of 9–10 August 1993 more than 150 luminous cloud-ionosphere discharges (CIs) were observed above a thunderstorm complex moving SE across the state of Iowa. Images of the CIs were obtained through clear air by intensified CCD TV cam
