This image is for latitude 50 degrees North. Looking primarily at the 2nd number in each pair (the altitude of the Sun at *solar noon* above due South)… *subtract* 12 degrees for solar elevation in the Upper Susitna Valley (62°N), and *add* 30° degrees for Hawaii. On April 25th the Sun is about 41° above due South at solar noon in Talkeetna/Trapper Creek. Image source: [http://www.physicalgeography.net/](http://www.physicalgeography.net/?ref=ktna.org)

In the Thursday 4/26 live-over-the-phone StarDate Susitna, Kathleen Fleming spoke about the Sun. This H-R diagram shows our star in the average, long-lived section, lucky for us life-forms. Not included in the show: approx. 85% of all bright stars are part of a multi-star system, which may be a bit too chaotic for a planet to develop life.
