The effects of energetic electron precipitation into the auroral region at a time of enhanced solar wind have been investigated during a continuous period of 24 h, using the European Incoherent Scatter (EISCAT) radar, an imaging riometer, and part

The investigation concerns the size and motion of spatial fine structure in auroral radio absorption as observed by imaging riometer. Electron density profiles in the D and E regions determined by simultaneous incoherent-scatter radar were inverted t

Intensity histograms of 14 EUV emission lines in a polar coronal hole, its equatorial extension, the Elephant's Trunk, and the adjacent quiet Sun regions have been obtained from SOHO/CDS observations made in August and September 1996. Differences bet

Intensities of 12 strong EUV emission lines in a coronal hole and the neighbouring quiet Sun region have been obtained from SOHO/CDS observations made in August and September 1996. The field of view is 1 arcmin wide by 4 arcmin, with a series of obse

We present results from SOHO/CDS and SOHO/SUMER coordinated observations of coronal streamers made during the spring 2000 quadrature of SOHO, the Sun, and Ulysses. These observations form part of the JOP 112, which is primarily aimed at investigating

Extreme ultraviolet observations of plumes in polar coronal holes are presented and their spectroscopic signatures discussed. The study focuses on the base of plumes seen on the disk of the Sun with the Coronal DiagnosticSpectrometer (CDS) on the Sol

High time resolution ( ≈ 13 s cadence) Solar and Heliospheric Observatory (SOHO) Coronal Diagnostic Spectrometer (CDS) Grazing Incidence Spectrometer (GIS) time series data is analysed for evidence of quasi-periodic variability in the solar corona.

We report results from the analysis of a sequence of SOHO/CDS observations obtained off-limb in the south polar coronal hole on 6 March 1998. Three successive data sets were obtained with the Normal Incidence Spectrometer(NIS), the first of which sho

An in-flight calibration study of the Coronal Diagnostic Spectrometer (CDS) instrument on board SOHO (Solar and Heliospheric Observatory) is presented. The relative intensity calibration of CDS is a funda- mental requirement for deriving important ph

A novel technique is presented that aids the reconstruction of solar coronal magnetic fields by augmenting the visible solar surface boundary conditions with an estimate of the simultaneous conditions on the far side of the Sun. In converting from li
