Video opazovanje Jupitra 13.07.1997

Video astronomy at Astronomical Society Javornik

Video imaging of the planets and the Moon is intensively performed by our member Igor Grom. Using a B&W CCD video camera and the Celestron 8 telescope he regularly tries to battle bad seeing conditions.

On 13 July 1997 an interesting event occured while imaging Jupiter at 5:44 local time (3:44 UT). A bright point of light (probably an artificial sattelite) zipped less than 1 arc minute from Jupiter. The angular speed was estimated to be 2.7 arc minutes per second. The object is seen at 27 still video frames and digitized images of some of them (1st, 5th, 10th, 15th and 20th) are presented here. The contrast of the original images was very poor, because the Sun was already rising at the time of exposure. So, the contrast was enhanced digitally.

Jupiter coordinates at the time of exposure were RA=21h31m58.6s, DEC=-15d33'53", azimut=219d23'19", altitude=19d40'30".
