A Lowell Digital Ionosonde (DPS-4) has been used at the Australian Antarctic polar cap station Casey (-80.6° CGM latitude) in a study of ionospheric polar cap patches.
An overview of the Davis station hydroxyl airglow temperature program will be given. Seasonal structure, planetary scale periodicities and inter-year variability determined from six years of hydroxyl airglow rotational temperatures will be presented. Solar cycle influences will be examined.
The period May 10-12, 1999 saw the solar wind density drop to very low levels, accompanied by a large expansion of the magnetosphere. A minimum density below one particle per cm3 was attained for several hours before the solar wind pressure returned to normal levels.
Noctilucent ("night shining") clouds can be a beautiful, awe-inspiring sight but they are viewed by some scientists as harbingers of mans impact on his environment. We use a rare sighting of a noctilucent cloud at Davis station (68.6S, 78.0E)…
Current research utilises the recently installed Southern Hemisphere Imaging Riometer (SHIRE) located at Australia’s Davis Antarctic station to study riometer signatures associated with cusp-latitude magnetic impulse events (MIE’s) detected in co-located fluxgate magnetometer data.
During the summer season 1997–1998 a GPS Ionospheric Scintillation Monitor (GISM) was installed at Casey station, Antarctica, 66.28°S, 110.24°E, -80.38 invariant latitude. This system is capable of tracking up to 11 GPS satellites at the L1 frequency of 1575.42 MHz.
