Sun overhead

The sun was directly overhead Bangalore.

Thanks to Prof. John Thorstensen’s excellent JSkyCalc software, I was able to calculate that the sun was directly overhead Bangalore today.

I think this is really cool.  As I live in the north, the sun is always to the south of us. Each year the sun processes further north in summer, and south in winter, but never passes overhead.  Here in the tropics, by definition, the sun passes overhead Bangalore (13° 01′ 23″ north, which I can read from Google Maps) on its way northward to the Tropic of Cancer (23° 26′ 22″ north), and then again on its way southward to the Equator and then the Tropic of Capricorn.  I missed the opportunity, unfortunately, to run outside at noon (local solar noon, of course, not noon IST) to see that my shadow was directly underneath me.  But now it’s kinda cool to think that the sun is north of me!
