The main effects seen at totality were therefore Baily's Beads
and the horizon colours.
We enjoyed a comfortable temperature and mounting excitement as the partial phase progressed, the light quality subtly changing, the birds' confusion growing until at second contact we were treated to some fine Baily's Beads
and multiple small prominences on the lower right aspect followed by a superbly detailed solar maximum corona and Venus blazing away to the upper left of the eclipsed Sun.
Then spectacular bursts of the Sun's first rays cut through the night, making the spectacular Diamond Ring, followed by Baily's Beads
as sun rays spike through the peaks on the surface of the Moon.
Just before totality, the moon acquires blobs of light known as Baily's Beads
, caused by sunlight shining through the moon's valleys and mountains.
The safe, fast, and easy removal and replacement of a filter can make all the difference when it comes to successfully capturing Baily's Beads
, the diamond ring, and the Sun's electric-pink chromosphere in the fleeting seconds at the beginning and end of totality.
At the symposium a total of 23 presentations was given on wide-ranging subjects including the history of occultation phenomena as seen from northern England, early observations of Baily's beads
seen during solar eclipses, accounts of successful grazing lunar occultations and asteroidal occultations, observations of mutual eclipses and occultations of the galilean moons of Jupiter, seasonal variation in the atmosphere of Pluto as probed by occultation and photometric studies, use of high-speed photometry to detect occultations involving Edgeworth-Kuiper belt objects, and accounts of various observing methods, accurate timing and software developments facilitating analysis.
The app will also use the phones' GPS metadata to obtain precise times for the events at totality's beginning and end, capturing the moments when bits of sunlight peek through valleys along the Moon's rugged limb to create the flashes known as Baily's Beads
A triangular aperture cut in cardboard was placed in front to produce diffraction spikes around Baily's beads
, while keeping clear images of the chromosphere and prominences (Figure 5).
The coming of the sudden shadow," the approach of the umbra, shadow bands, Baily's Beads
, the chromo-sphere and flash spectrum, totality, the corona, "the eye of God," coronal loops and streamers, darkness at midday, the "360[degrees] sunset," the (ruby-red) solar prominences, the eclipse wind (and temperature drop), planets and stars visible in a midday sky of midnight blue--and what I take to be the most staggering sight in all of astronomy: the diamond ring.
