What is the latitude of the sub solar point on March 8 2016?

Answer 1

At 0000 UT (Greenwich) on March 8 2016, the sun's declination will be -4.7997°.
24 hours later, at 2400 UT on March 8, the sun's declination will be -4.4088°.

So the sun will move from 4.7997°S to 4.4088°S latitude during the 24 hours
of March 8, 2016 in the Greenwich time zone.

With the software I'm getting these numbers from, it looks like the sun will
cross the equator and end Winter/begin Spring in the northern hemisphere
at 0521 UT on March 20.

A few days before that, when it starts showing up on the newspaper's weather page,
I guess I'll find out if this software is worth anything.
