1. SolarView User Manual July 2009 6 3 3 Noontime In everyday language noontime is the time of day at which the clock shows 12 00 In SolarView noontime is the point at which the sun s altitude above the horizon 1s at its greatest In many cases these two times of day diverge For example Finland s time zone is UTC 2 and in Finland the sun is at its highest at 12 00 noon only on the 30 meridian east which bisects East Finland through the town of Lieksa In Helsinki for example noontime is 20 minutes later and in Ecker in Aland over 40 minutes later Because SolarView uses precise coordination data it is capable of displaying the exact noontime and the sun s altitude above the horizon at noon 3 4 Morning and evening twilight In SolarView twilight is defined as so called civil twilight during which the sun is at most six degrees below the horizon In astronomy there are usually several degrees of twilight between civil twilight and complete darkness Civil twilight The sun is 0 6 degrees below the horizon Both the brightest stars and planets such as Venus become visible The term civil twilight is derived from the fact that during the middle ages craftsmen of burghers were still able to work at this time of day without artificial light Nautical twilight During nautical twilight the sun is 6 12 degrees below the horizon The term derives from the ability in the past of seafarers to use2. 14 779 azimuth 162 725 altitude at noon 16 07 12 34 pm sunrise 8 07 am sunset 5 01 pm time 12 02 2009 11 25 05 am Figure 5a 5b Sun Position View at the same observation time in the northern hemisphere from Finland 60921 50 N 25 05 51 E and in the southern hemisphere from Namibia 17 58 44 S 12 02 34 E The times are set at Finnish time UTC 2 At the time of writing this paragraph at 14 29 53 on the 6 of October 2008 SolarView showed that from the author s backyard 60921 50 N 25 05 51 E the sun was 22 32 above the horizon and its azimuth 202 21 1 e a little to the west of due south SolarView User Manual July 2009 12 Size of sun To make it easier to see the sun is depicted as disproportionately large on screen In SolarView it has a diameter of 12 pixels which on a display 240 pixels wide would correspond to a size of 18 when its true diameter in the sky is 32 This means that the sun shown on a 240 pixel display is over 33 times larger than in nature Simulation mode In simulation mode you can move backwards and forwards through time and view the sun s position in the sky during various times of the day or year SolarView Sun Position SolarvView Sun Position SolarView Sun Position altitude 3 97 azimuth 338 07 altitude at noon 53 057 1 21 pm sunrise 3 51 am sunset 10 51 pm altitude 52 539 azimuth 166 47 altitude at noon 53 05 1
