(Submitted on 9 Sep 1999). Abstract: The brightness of the The median sky brightness at high elevation, high galactic latitude and high ecliptic latitude, at sunspot minimum, is B = 22.7, V = 21.9, R = 21.0, similar to that at other dark sites. The Night Sky Show will take you on an epic journey from our celestial back yard and across A show for anyone with a slight interest or more in the night sky. Sir Patrick Moore's final Sky At Night appearance, filmed very shortly before his death in December 2012.
