美麗的日蝕

美麗的日蝕
Tuesday, July 2


New Moon occurs at 3:16 a.m. EDT. At most New Moons, our satellite tracks across the sky with the Sun and remains
hidden from view. But today, the alignment between the Moon and Sun is perfect and people in the right locales can view a
solar eclipse. Observers across much of South America and the South Pacific Ocean will see the Moon take at least a bite
from the Sun. But people along a narrow path that runs from the Chilean coast near La Serena to the southern suburbs of
Buenos Aires will witness a total eclipse, in which the Moon completely blocks the Sun’s disk. People watching the partial
phases of the eclipse need to use safe solar filters to view it directly, but no eye protection is needed during totality.

During the 2nd contact of the Total Solar Eclipse in 2017, a Corona (atmospheric optics with the rainbow colour) appeared around the Diamond Ring, with Shadow Bands casting within the corona (the stripes on both sides of the Corona).
A thin layer of cloud in between the sun and ground is believed to have allowed the projection of the Corona and Shadow Band.
While a thin layer of smoke from a wild fire may have also contributed to the cause.
