Solar eclipses -- 1869
"The time both of the beginning and end of totality, for reasons
verbally stated to you, I failed to note. Of the phenomena during
totality, those which I most noted were, first, the disappearance
of the last rays of the sun in an irregular broken line of light,
succeeded at or near this point by a band or corona of a silvery
white light almost as bright as the face of full moon. This though
much wider at this point than elsewhere, was soon observed to extend
in an entire ring around the dark body of the moon; from this luminous
ring, rays of light seemed to shoot out at right angles on every
side, diverging as it were from the centre of it. In some places
they seemed to extend out nearly half the diameter of the moon
from the bright ring; in others, not one fourth so far. But the
most remarkable appearance of all, and that which attracted the
attention of every one who witnessed the eclipse, whether seen
with the naked eye or with the telescope, were the red protuberances
that shot up immediately on the disappearance of the sun, from various
places, on the edge of the moon; their position your photograph will
fix better than I describe. The largest was on the lower edge of
the moon, and was by my estimate, when highest, not less than two
minutes in altitude from the edge of the moon, or about 55,000 miles.
Its colour was a bright _pinkish red_, its outlines were well defined,
and were not curves, but rather irregularly-broken straight lines,
and throughout it seemed marked by similar lines. It reminded me of
the appearance one sometimes sees on the face of a cliff where the
rock is broken by horizontal and vertical lines. The same or nearly
the same appearance would be presented if one were to view columnal
basaltic rocks, from a point where the rocks in the rear would rise
above those in front. I would therefore suggest whether these lines
may not have a similar origin, and each be the outline of a vast
column of luminous matter thrown up above the atmosphere of the sun.
There was a constant fluctuation in the height of these coloured
protuberances during the total eclipse; the large one was the only
one that was seen throughout the whole time, and that remained
visible for some time after the edge of the sun appeared.
The general phenomena, such as the darkness, the shining of the
stars, &c, I had less opportunity of noticing than yourself and
others, who were without a telescope, and will therefore say nothing
about them. I have made no attempt to put my observations into any
regular form, but have hastily written such as I thought might be
of use to you, leaving it entirely to you to make any use of them.
"Very truly yours,
"HUGH D. VAIL."
