EISCAT observations of plasma patches at sub-auroral cusp latitudes
A sequence of 3 patches of high-density (1012 m−3) cold plasma on a horizontal scale-size of 300– 700 km was observed near magnetic noon by the EISCAT VHF radar above Svalbard on 17 December 2001. The patches followed a trajectory towards the cusp inflow region. The combination of radar and all-sky observations demonstrates that the patches must have been segmented equatorward of the cusp/cleft...
متن کاملLetter to the Editor Geomagnetic storm eects at low latitudes
The geomagnetic horizontal (H) ®eld from the chain of nine observatories in India are used to study the storm-time and disturbance daily variations. The peak decrease in storm-time variation in H showed signi®cant enhancements at the equatorial electrojet stations over and above the normally expected decrease due to the ring current eects corrected for geomagnetic latitudes. The disturbance da...
متن کاملSimultaneous measurements of high-frequency pump-enhanced airglow and ionospheric temperatures at auroral latitudes
Simultaneous measurements of enhanced airglow at 6300 Å and plasma temperatures from transmitting a powerful high frequency electromagnetic pump wave from the EISCAT-Heating facility into the ionospheric F region at auroral latitudes are reported. The airglow was detected with the Auroral Large Imaging System in northern Sweden and the background plasma parameter values were obtained with the E...
متن کاملSplash Albedo Protons Between 4 and 315 MeV at High and Low Geomagnetic Latitudes
The differential energy spectrum of splash albedo protons has been measured at high geomagnetic latitude near Fort Churchill, Manitoba, at three periods of the solar cycle in 1966, 1967, and 1969 and at low latitude near Palestine, Texas, in 1967 by using a balloon-borne solid state detector telescope. We observed splash albedo proton fluxes between 4 and 315 MeV of 81 + 11, 70 + 11, and 48 + 8...
متن کاملLow frequency geomagnetic field variations at Dome C (Antarctica)
We conduct an analysis of the geomagnetic field variations recorded at the new Antarctic station Dome C, located very close to the geomagnetic pole, which has been operating for approximately one month during the 1999–2000 campaign. We also perform a comparison with simultaneous measurements at the Italian Antarctic station Terra Nova Bay, in order to investigate the spatial extension of the ph...
