Using soft x-ray observations of the bright new comet C/1999 S4 (LINEAR) with the Chandra x-ray observatory, we have detected x-ray line emission created by charge exchange between highly ionized solar wind minor ions and neutral gases in the comet's coma. The emission morphology was symmetrically crescent shaped and extended out to 300,000 kilometers from the nucleus. The emission spectrum

O'Mahoney (Isaac Newton Group of Telescopes) on Aug. 1.9 UT with the Wide Field Camera on the 2.5-m Isaac Newton Telescope, shows no evidence of a nuclear condensation or subnuclei within the coma.

Cometa Linear C/1999 S4: La cometa 1999S4 venne scoperta il 27 settembre 1999 dal team del Lincoln Near-Earth Asteroid Reseach (LINEAR project), mediante uno dei suoi strumenti automatizzati da circa un metro di diametro situati nel New Mexico (USA). 2020-08-16 · Explanation: Comet C/1999 S4 LINEAR is only one of many comets discovered with the Lincoln Near Earth Asteroid Research (LINEAR) telescope operating near Soccoro, New Mexico, USA. Traveling steadily southward through Earth's night sky, C/1999 S4 passed perihelion (closest approach to the Sun) yesterday on what is likely its first trip through the inner solar system . Comet C/1999 S4 (LINEAR) showed a very special behaviour between 28 June and1 July 2000.
