Election in Pune and Zero shadow day

Today is election day in Pune (Lok Sabha), and I voted.

Today is also a ‘zero shadow day’ in Pune. The sun is exactly over our head (zenith), and no angle is subtended by the shadow. In the pic, the sun is captured at its zenith.

Caution: don’t look at the sun directly. This image was captured wearing filtered glass

Check the webpage of the Astronomical Society of India linked below. It has some good explanations and geographical locations in India where zero shadow day is observed.

As a scientist, professor, writer & podcaster of physics & its history & philosophy......I am interested in the historical and philosophical evolution of ideas and tools in the physical sciences and technology. I research the intellectual history of past scientists, innovators, and people driven by curiosity, and I write about them from an Indian and Asian perspective. My motivation is to humanize science.
