Hello everyone,
On Saturday, I travelled from Miami to the Dallas / Forth Worth area to watch the eclipse. I had made the reservations at the beginning of the year because all hotels and car rentals in the area were sold out for the weekend.
I ended up watching the eclipse at the DFW airport garage roof, where there were about fifty people watching including two companion dogs. I used marine plastic sextant.
In the Dallas area, the total coverage took place around 18:44 UTC. After the eclipse, I calculated the GHA and declination of both the sun and moon with the following results:
GHA Sun: 100° 35.6’
GHA Moon: 100° 31.5’
Declination of the Sun: 7° 36.0’ N
Declination of the Moon: 8° 1.7’ N
It is also interesting to notice that before the eclipse, the Moon declination was lower than the Sun, it reached the same declination before the total eclipse time and surpassed it after that.
I guess that would explain why the moon coverage went from the lower right to the upper left, and also because the moon moves in the sky at a rate 14.48°/hour instead of the sun that moves at a rate of 15°/hour, so the moon moves in the sky to the left relative to sun. (Sorry for using the words left/right instead of east/west because I think it is more intuitive in this case).
Anyway, my analysis could be wrong, so as usual I am open to any comments.
Thanks!
