Ближче до Землі комета підійшла 22 липня 2000 року, на відстань 0,3724 a. о. (55 млн км). 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 .

It was observed by visual, photographic and CCD comet c/1999 s4 (linear) M. Kidger, Instituto de Astrofisica de Canarias, reports analysis of continued observations of C/1999 S4 at La Palma: "A 100-s exposure in R, taken by R. Corradi and N. 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.

WikiProject Solar System (Rated Start-class, Mid-importance) This article is within the scope of The evolution of the morphology of C/1999 S4 (LINEAR) is examined from aseries of images taken from shortly before the disruption of the nucleus until10 days afterwards. This is combined with light curve data to provide a uniquedocumentation of the early evolution of the disruption event. Download Citation | Comet C/1999 S4 (LINEAR) | IAUC 7418 available at Central Bureau for Astronomical Telegrams. | Find, read and cite all the research you need on ResearchGate Comet C/1999 S4 (LINEAR) showed a very special behaviour between 28 June and1 July 2000. Optical observations of the dust coma in two distinct continuum bandsrevealed that it changed morphologically as well as in colour. Comet C/1999 S4 (LINEAR), hereafter called S4, was discovered on September 27, 1999 by the Lincoln Near Earth Asteroid Research (LINEAR) program at heliocentric distance r = 4.3 AU. The ephemeris predicted that the comet would be as close to the Earth as ∆=0.364 AU just a few days before perihelion on 26 July 2000 (r = 0.765 AU). mode,wedetectedweakHCNJ ¼ 1 0 emission from comet C/1999 S4 (LINEAR) at 14 4mKkms1 averaged over the 14300 beam.

The comet C/1999 S4 was expected to be a moderately bright object during summer 2000. It was observed by visual, photographic and CCD techniques. The derived light curve shows that the comet reached a brightness maximum (mag. 6 around July 26) corresponding to the total dissolution of its nucleus. From the analysis of the light curve a double maximum was detected, the dissolution event
