Dayside optical and magnetic correlation events
Autor: Stephen B. Mende, J. H. Doolittle, Louis J. Lanzerotti, Harald U. Frey, Carol G. Maclennan
Publikováno v: Journal of Geophysical Research: Space Physics. 106:24637-24649
Sudden, short-lived dayside auroral activity is often observed equatorward of the quiescent auroral oval. Several cases from the 1996 South Pole and United States Automatic Geophysical Observatory data were examined. In all cases the optical events w

Analysis of conjugate data from extended magnetometer networks in northern and southern high latitudes is used to elucidate the initiation and the evolution of a magnetic impulse event (MIE) on June 6, 1997. In addition, data from all-sky imagers, im

The aurora during the passage of the May 27, 1996 magnetic cloud
Autor: J. H. Doolittle, T. J. Rosenberg, Allan T. Weatherwax, Harald U. Frey, H. B. Vo, Stephen B. Mende
Publikováno v: Geophysical Research Letters. 25:2605-2608
On May 27, 1996 two all-sky cameras in Antarctica observed the aurora during the passage of a magnetic cloud. Compression of the magnetosphere by the solar wind dynamic pressure pulse in front of the magnetic cloud caused a short, strong, and localiz

Substorm precipitation in the polar cap and associated Pc 5 modulation
Autor: T. J. Rosenberg, J. H. Doolittle, C. G. Maclennan, Allan T. Weatherwax
Publikováno v: Geophysical Research Letters. 24:579-582
This paper reports substorm-related cosmic radio noise absorption events observed deep into the polar cap, well poleward of the typical nightside auroral oval. We find that such events usually occur in the late expansion/recovery phase of a substorm

Southern Hemisphere poleward moving auroral forms
Autor: Easan Drury, Harald U. Frey, J. H. Doolittle, Stephen B. Mende
Publikováno v: Journal of Geophysical Research. 108
[1] This paper presents a statistical study of Southern Hemisphere poleward moving auroral forms (PMAFs) using optical data from the US Automatic Geophysical Observatory network in Antarctica. These Southern Hemisphere events are compared with Northe

Correlation between λ4278-Å Optical emissions and a Pc 1 Pearl Event observed at Siple Station, Antarctica
Autor: J. H. Doolittle, A.C. Fraser-Smith, Laurence J. Cahill, W.C. Armstrong, Stephen B. Mende, Roger L. Arnoldy
Publikováno v: Journal of Geophysical Research: Space Physics. 85:1194-1202
Detailed correlations were observed between the amplitude envelope of Pc 1 pulsations and zenith 4278 N/sub 2//sup +/ intensity at Siple Station, Antarctica, (L=4.2) on August 1, 1977. Conjugate Pc 1 data at Roberval show a similar amplitude envelope

Photometric evidence of electron precipitation induced by first hop whistlers
Autor: J. H. Doolittle, D. L. Carpenter
Publikováno v: Geophysical Research Letters. 10:611-614
Electron precipitation events induced by discrete VLF whistler mode waves have previously been detected by photometers at Siple Station, Antarctica. This paper presents the first observations of ionospheric optical emissions correlated with VLF waves
