A long series of polar patches was observed by ionosondes and an all-sky imager during a disturbed period (Kp = 7- and IMF Bz < 0). The ionosondes measured electron densities of up to 9 × 1011 m-3 in the patch center, an increase above the densi

Ionospheric signatures of coupling between solar wind Alfven waves and the dayside magnetosphere were observed near the cusp footprint. These included flow channel events and poleward progressing DPY currents. A long series of highly structured polar

Dynamic and intense polar auroras were observed over Eureka, Canada (88.9°N magnetic) through January 10 and 11 following the solar coronal mass ejection (CME) of January 6, 1997. A dusk sector arc appeared by 0200 UT on January 10 following the arr

Optical images of [O I] 630.0-nm emission from drifting F region polar patches acquired with a sensitive all-sky imager have been analyzed to infer the ionospheric convection velocity over a period of 9 hours on December 8, 1993. The drift vectors ag

We have performed model calculations of far ultraviolet (FUV) auroral emissions, their radiative transfer, and the responses of the two cameras of the Viking UVI to these emissions for comparison with a small sample of Viking images with complementar

An investigation was carried out to assess the value of ultraviolet auroral images for remote sensing of electron precipitation. We compared auroral images, obtained by both cameras of the Viking Ultraviolet Imager during April and early May 1986, wi

Ground-based auroral observations with a meridian-scanning photometer and all-sky camera were made at Rabbit Lake, Saskatchewan, Canada, simultaneously with nearby HILAT satellite passes during six winter periods near new moon from 1984 to 1986. Eigh

A Black Brant IV rocket was flown through the dayside cusp from Cape Parry, N.W.T., (λ = 75°) on December 6, 1981. It flew to an apogee of 603 km and emerged into the polar cap at λ = 77°. The flight was through a fairly stable midday cusp at app
