YPeriodic substorm activity in the geomagnetic tailOn 19 May 1978 an unusual series of events is observed with the Quadrispherical LEPEDEA on board the ISEE-1 satellite in the earth's geomagnetic tail. For 13 hours periodic of both bursts of both ions and electrons are seen in all the particle detectors on the spacecraft. On this day periodic activity is also seen on the ground, where multiple intesifications of the electrojets are observed. At the same time the latitudinal component of the interplanetary magnetic field shows a number of strong southward deflections. We conclude that an extended period of substorm activity is occurring, which causes repeated thinnings and recoveries of the plasma sheet. These are detected by ISEE, which is situated in the plasma sheet boundary layer, as periodic dropouts and reappearances of the plasma. Comparisons of the observations at ISEE with those at IMP-8, which for a time is engulfed by the plasma sheet, indicate that the activity is relatively localized in spatial extent. For this series of events it is clear that a global approach to magnetospheric dynamics, e.g., reconnection, is inappropriate.

DThe temporal evolution of a small auroral substorm as viewed from high altitudes with Dynamics Explorer 1Observations"A small auroral substorm is investigated with auroral imaging photometers carried on the spacecraft Dynamics Explorer 1. Initial brightening along the auroral oval and the subsequent westward and poleward motions of intense, localized emission regions are associated with auroral surges. Following substorm onset, another region of less intense emissions is observed to develop at lower latitudes and adjacent to the bright region near local midnight. This second region expands towards the east. The bright zone of auroral emissions associated with the surges is interpreted as the signature of electron acceleration along magnetic field lines threading the boundary layer of the plasma sheet in the magnetotail. The more diffuse, less intense region is identified with eastward-drifting electrons injected into the plasma sheet and ring current following substorm onset. No rapid poleward motion of the discrete aurora is detected during substorm recovery."--NTRS abstract602ocn021966737book19890.93Gurnett, Donald AAuroral plasma waves591ocn021993377book19880.93Plasma diagnostics package. final report592ocn011729816book19830.93Effects of chemical releases by the STS-3 orbiter on the ionsphere581ocn021993188book19880.93Plasma diagnostics package. final science project581ocn021993284book19880.93Plasma diagnostics package. final science report551ocn012172072book19830.92Gurnett, Donald A[Reduction and analysis of data from the plasma wave instruments on the IMP 6 and IMP 8 spacecraft] final report for NASA contract NAS5-26125551ocn011654268book19830.92Research in space physics at the University of Iowa annual report for 198241ocn122329191book19710.96Frank, Louis AOn the distributions of plasmas and electric fields over the auroral zones and polar capsSimultaneous observations of DC electric fields and low-energy charged particles at low altitudes over the earth's auroral zones and polar caps were obtained with the satellite Injun 5. Several of the principal results for the evening and dawn local time sectors are summarized41ocn039071655book19750.97Saflekos, Nicolaos AEntry of low-energy solar protons into the earth's magnetotailThe access of low-energy solar protons (E sub p> 0.3 MeV) from the interplanetary medium into the earth's magnetotail was studied using observations obtained by Explorers 33, 34, and 35 over a 4.5 year period. Emphasis is on events whose intensity-time profiles exhibit sharply defined discontinuities observed by at least one of the three spacecraft in the interplanetary medium and another within the magnetotail42ocn233145116book19730.96Sentman, Davis DBasic elements of power spectral analysis41ocn004222198book19690.96Schield, M. ADrift of noninteracting charged particles in a simple geomagnetic fieldThe corotation of plasmas within the plasmasphere has been observed and the existence of a potential difference across the magnetosphere in the dawn-dusk meridian of several tens of kilovolts is consistent with various geophysical observations. The purpose of the paper is to solve analytically the drift motion of noninteracting charged particles, mirroring equatorially in a rotating magnetic dipole-field, across which is superimposed a uniform electric field41ocn122939399book19710.96Gurnett, Donald AELF noise bands associated with auroral arcs31ocn085781077book19690.92Frank, Louis ALow-energy proton (0.5 [less than or equal to] E [less than or equal to] 50 keV omnidirectional intensity contours in the earth's outer radiation zone at the magnetic equatorObservations of low-energy proton intensities within seven selected energy bandpasses spanning the energy range 0.5 <E <50 keV are summarized in L-value versus time diagrams for the period 10 June through 23 July 1966. These contours of omnidirectional, differential proton intensities were calculated via measurements of the directional, differential spectrums of the proton intensities with a sensitive electrostatic analyzer array borne on the earth-satellite OGO 3 at mid- and low latitudes in the outer radiation zone and are normalized to a geomagnetic latitude 0 deg. (magnetic equator). These L-versus-time diagrams provide a compact, useful summary of these unique observations of proton intensities over L-values ranging from 3.0 to 12 and promote further insight into the morphological features of one of the most dynamically important components of magnetospheric plasma.
