    Near-infrared sky background fluctuations at mid- and low latitudes

    The emission of the upper atmosphere introduces an additional variable component into observations of astronomical objects in the NIR 700–3,000 nm range. The subtraction of this component is not easy because i...

    Spectroscopic study of comet Halley by the Vega 2 three-channel spectrometer

    The three-channel spectrometer (TKS) aboard the Vega 2 spacecraft recorded infrared and visible spectra near the nucleus of comet Halley. Spectra in the range 0.95–1.9 µm at a distance of 300 km from the nucle...

    Near-ultraviolet and visible spectrophotometry of comet Halley from Vega 2

    We report results obtained by the near-ultraviolet and visible channel (V) of the TKS instrument1 carried by Vega 2 during the hour preceding its closest approach to comet Halley. The brightness of the OH (0, 0) ...
