Eclipsed Moon and Alnath (Beta Tauri)

Alnath (β Tau) and the eclipsed Moon -1 sec exposure

JISHOU, HUNAN — I caught the total lunar eclipse about halfway through totality. I didn’t do all the good stuff, like wait for the equipment to cool to ambient temperature (0°C here), because I almost forgot to go out. So, out of 25 shots I got three halfway decent ones. The focus seems to be a bit off, I fear.

The three images here are of the Moon toward the end of totality. You can just barely see it brighten on the lower right edge as it leaves the Earth’s shadow. The star to the left is Alnath (β Tauri), the second brightest star in Taurus. Alnath is a bluish-white B-class star, about 700 times brighter than the Sun, 4.5 times heavier and 5 times bigger. It’s 131 light-years away.

I used a tripod-mounted Nikon D60 with a 70-300 Tamron zoom lens at 70 mm, f5.6, ASA 200. The three exposures are 1.0 sec (above), 1.6 sec and 2.5 sec (below).

Alnath and Eclipsed Moon - 1.6 sec exposure

Alnath (β Tau) and eclipsed Moon - 1.6 sec exposure

Alnath and eclipsed Moon - 2.6 sec exposure

Alnath (β Tau) and eclipsed Moon - 2.6 sec exposure

Totality ended around 11:00 pm here.

Fernanda Torres in Casa de areia
Caption: Áurea (Fernanda Torres) talks to Luiz (Enrique Diaz) in Casa de areia.

On our day off Monday, I ended up watching TV in the afternoon and stumbled upon a Brazilian movie on Starz, Casa de areia (House of Sand), that to my surprise had references to Einstein’s relativity theory in it.

The plot is minimal. The movie’s effect comes from the acting and the ironic turns in its main characters’ lives.

Áurea is a young, city-bred woman whose husband has the crackbrained idea of moving to a godforsaken plot of land on Brazil’s arid northeast (O Nordeste). Her mother, Dona Maria, accompanies them. The husband dies before the birth of Áurea’s only child, Maria, leaving the women essentially stranded in the middle of nowhere.

Áurea wants to leave in the worst way, while Dona Maria would prefer to stay. There are no men to tell her what to do, Dona Maria says. After nearly a decade stuck in O Nordeste, Áurea arranges to leave with a wandering peddler who sells salt and other sundries to the few people living in the region.

But the peddler dies en route to the women’s house. Áurea and their neighbor, a reserved man named Massu, go in search of the peddler. Along the way, Áurea tells Massu she will finish the trip on her own, following tracks in the sand. After two days, she comes across the campsite of a group of scientists photographing the solar eclipse of 1919.
