Psalm 19:1 "The heavens declare the glory of God; the skies proclaim the work of his hands."
Literally awe inspiring.
I shared this back on April 8th, 2024 on our Google Group, but here are the pics and data for others to enjoy.
Here in Indianapolis we had 4 minutes of totality
It was great watching the temperature and UVA and
UVB drop and then rise again.
Here is a link to the TI-Nspire file of the data. It has been updated with some pictures and questions for my students. For example (the answer can be found at the bottom of this article):
Ultraviolet
A (UVA) has a longer wavelength (320-390nm). It is associated with skin
aging. Ultraviolet B (UVB) has a shorter wavelength (290-320nm). It is
associated with skin burning.
Here are the two screen captures of data during the beginning, from about 5% to 80% partial eclipse.
Then here is the 16 minutes entering into totality
And starting during totality, here is the 1 hour and 12 hours of data as the sun reappears.
The corona was amazingly beautiful. We also easily saw Venus and Jupiter.
The
temp dropped from 26.1 deg Celsius to 20.5 and then back up to 26.1.
That is a drop from 79.0 deg F to 68.9 deg F back up 10 deg F in that
hour after.
The diffraction (holes in aluminum foil
viewed in a box) in the shape of a heart ... partial eclipse of the
heart, entering into totality and leaving it.
I
thought the ring stand set up was a pleasant design. In this last pic
you can also see refraction (binoculars) and the diffraction box.
