Before his unseemly run-in with the microwave, the distant, brooding father, James Orin Incandenza, a former junior tennis star and a retired physicist who pioneered cold fusion by hamessing the dark power of - you guessed it - annularity
, founded the Enfield Tennis Academy, and then took up a career as an "apres-garde" filmmaker.
In larger scopes, a ring structure is apparent as the center darkens to show annularity
when a filter is applied to the view.
At 276x the annularity
is easier to see, and the galaxy behind its northern edge looks a bit too straight to be part of the ring.
There the Sun will be a good 22" above the western horizon, and annularity
will last 4 minutes 47 seconds as seen from the centerline.
With a narrowband or O III filter, the 10-inch scope at 220 x shows traces of annularity
in NGC 2610.
This results in a thick annular ring of sunlight surrounding the Moon at mid-eclipse and a rather broad path within which annularity
is visible, ranging from 147 to 201 miles (237 to 323 km) in width.

NGC 6337 in Scorpius, depicted at left and charted on page 58 of the Pocket Sky Atlas, is nicknamed the Cheerio Nebula and gives a better hint of annularity
, with some observers unabashedly describing a ring.
Brooke Comber noted that shadow bands were not seen during the eclipse and made detailed sketches of Baily's Beads (seen at left) at the beginning and end of annularity
. By all accounts, the expedition team enjoyed a fine view of the eclipse--and then it was back to work observing Mars.
I can confirm the annularity
with a filtered view through my 10-inch scope at 213x.
These small tropical countries on the northern coast of South America were the only solid ground touched by the path of annularity
at sunrise that day; the rest of the narrow, 13,800-kilometer-long (8,600-mile) track traversed the open waters of the South Atlantic.
, the partial phases took over once again.
To record the foreground, a normal (unfiltered) exposure was taken a few minutes after annularity
As a result the maximum duration of annularity
will be a lengthy 4 minutes 31 seconds, when the Sun is high overhead in central Sudan.
"It had been raining the whole day; it stopped only 15 to 20 minutes before annularity
, which lasted only 12 seconds."
