Solar zenith angle minutes of arc, which is less than the apparent angular radius of the sun. The formula also neglects the effect of atmospheric refraction. Sunset and sunrise occur (approximately) when the zenith angle is 90°, where the hour angle "h" satisfies Precise times of sunset and sunrise occur when the upper limb of the Sun appears, as refracted by the atmosphere, to be on the horizon. A weighted daily average zenith angle, used in computing the local albedo of the Earth, is given by where "Q" is the instantaneous insolation. For example, the solar elevation angle is : An exact calculation
Less Than Jake as landing the opening spot on Bon Jovi's North American tour. While it was neither as commercially successful as previous releases initially, the album contained singles such as "Look What Happened" (which received minor airplay on college stations) and the group's home-town anthem, "Gainesville Rock City" (which received some airtime on MTV2). Shortly after the album's recording, Derron Nuhfer left the band (going on to join Gunmoll and later Escape Grace), and Less Than Jake found a replacement in former Spring Heeled Jack saxophonist, Pete Wasilewski. To avoid the confusion provided by having two Peters within the band, the second
