Anisotropic pitch angle distribution of 50 eV to 50 keV particles at synchronous altitude.
At times, the electron pitch angle distributions at synchronous orbit have been observed to be highly anisotropic. In the local morning region, distributions concentrated near 90 deg are often observed in particles of less than approximately 2000 V. This anisotropy decreases with increasing energy from 1 keV to the detector's limit at 50 keV. The time development of anisotropy is consistent with production by pitch angle scattering processes which are not effective on electrons with small velocities parallel to the magnetic field. Another type of distribution has been observed with the low-energy (below 1000 V) electrons concentrated parallel and antiparallel to the magnetic field. These distributions are only seen in the dusk sector, but this may be an orbital artifact.

The latitudinal morphology of 10-eV to 10-keV electron fluxes during magnetically quiet and disturbed times in the 2100-0300 MLT sector
Electron and proton data from Isis 1 and 2 have been used to examine the change in the latitudinal morphology of auroral particle fluxes as a function of substorm time in the dipole magnetic local time period from 2100 to 0300. Clear and repeatable systematics in the latitudinal morphology were observed during the various phases of a substorm, allowing the substorm phase to be identified on the basis of particle data alone. Based on this study, a new phenomenological substorm model is presented which relates particle precipitation from various parts of the magnetotail to auroral oval morphology.
