Annular solar eclipse in Benjamin Constant

Amazonas, Brazil

Benjamin Constant is inside the path of annularity. On Wednesday, January 26, 2028 the Moon sits wholly inside the Sun's disc for 9 min 25 s, starting at 08:52:35 local time (UTC-5), leaving a ring of sunlight around it (the "ring of fire"), with the Sun 45° above the horizon. Even then 84% of the Sun is covered at most, so the sky only dims, and the ring is still too bright to look at without eclipse glasses.

Annularity: 9 min 25 s
Annularity begins: 08:52:35 UTC-5
Sun at maximum: 45° up, ESE (112°)
Magnitude: 0.954
Sun covered at most: 84%
Whole eclipse: 07:18 to 10:58
From the central line: 14 mi (23 km)

Eclipse times in Benjamin Constant

Each phase of the eclipse in Benjamin Constant: local time, universal time, and the Sun's height and direction
Phase	Local time (UTC-5)	UT	Sun
C1: the partial eclipse begins	07:18:13	12:18:13	22° up, ESE (108°)
C2: annularity begins (the ring of fire)	08:52:35	13:52:35	44° up, ESE (112°)
Maximum eclipse	08:57:17	13:57:17	45° up, ESE (112°)
C3: annularity ends	09:02:00	14:02:00	46° up, ESE (113°)
C4: the eclipse ends	10:58:28	15:58:28	71° up, SE (138°)

C1 to C4 are the four contacts: the Moon first touching the Sun, the start and end of annularity (C2 and C3, only inside the path), and the Moon leaving the Sun. Magnitude is the share of the Sun's diameter the Moon covers at maximum; the share of the Sun's area covered is 84%. Sun direction is the compass bearing from true north.

Times are computed: check before you travel. They come from our own calculation (astronomy-engine, the same Moon and Sun sizes and Delta T as NASA's predictions) and agree with NASA's published central-line durations to within a second, but they leave out the mountains and valleys on the Moon's edge (NASA: about 1 to 3 seconds of annularity, and 1 to 3 km at the edges of the path), your exact spot in town and the weather.

Eye safety

Look at the partly eclipsed Sun only through eclipse glasses or a handheld solar viewer that meets the ISO 12312-2 standard. Ordinary sunglasses, even very dark ones, are not safe.
An annular eclipse is never safe to look at without eye protection, not even at annularity. At its greatest the Moon leaves a ring of the Sun's bright surface showing (the "ring of fire"), and looking at it without a solar filter can cause serious eye injury. Keep the glasses on the whole time you look at the Sun, from the first contact to the last: there is no moment to take them off.
Never look through a camera, binoculars or a telescope at the Sun, even with eclipse glasses on: those need their own solar filter fitted on the front.
Check the glasses before you use them and throw away any that are scratched, torn or damaged. Watch children while they use them.
