Just In Time For the Eclipse

“[O]n Sunday November 3rd, we will have the New Moon and Solar Eclipse in Scorpio. Solar eclipses usually indicate new beginnings, new perspectives, and possibly sudden changes, all of which require an ending or death of something old to make way for the new. All this emotional disorder, confusion, and hasty change is not to be feared.”  Julianne Victoria

Solar Eclipse 2013 November: When and Where to Watch
By The Epoch Times

The solar eclipse in 2013, on November 3, is a rare one. The hybrid eclipse doesn’t happen often–only once this year. And the next solar eclipse won’t happen until April 2014.

People in numerous areas around the world will be able to see this eclipse. Some will even see a total eclipse. In far-eastern North America, the Caribbean, and the northwestern tip of South America, the eclipse will be viewable beginning at sunrise.

In America, the western limit of the eclipse runs through southern Ontario, Ohio, Kentucky, Tennessee, Alabama, and the Florida Panhandle.

The eclipse will last about 45 minutes in most places. Times include:

United States

-6:22 a.m. through 7:12 a.m. in Boston

-6:29 a.m. through 7:11 a.m. in New York City (about the same in Washington D.C.-

-6:31 a.m. through 7:02 a.m. in Miami

-6:50 through 7:10 a.m. in Akron, Ohio

Canada

-6:35 a.m. through 7:12 a.m. in Montreal

-6:50 a.m. through 7:11 a.m. in Toronto

-7:10 a.m. through 8:15 a.m. in Halifax

Africa

-10:40 a.m. through 12:16 p.m. in Dakar, Senegal

-12:49 p.m. through 5 p.m. in Lagos, Nigeria

-1:15 p.m. through 2:36 p.m. in Algiers, Algeria

-2:30 p.m. through 3:25 p.m. in Tripoli, Libya

-3:00 p.m. through 3:58 p.m. in Cairo, Egpyt

-4:10 p.m. through 5:24 p.m. in Addis Abeba, Ethiopia (about the same for Nairobi, Kenya)

Europe

-1 p.m. through 2:10 p.m. in Madrid

-3:08 p.m. through 4:04 p.m. in Athens, Greece

Middle East

-3:12 p.m. through 4:43 p.m. in Jerusalem

-3:19 p.m. through 4:09 p.m. in Ankara, Turkey

-4:10 p.m. through 5:11 p.m. in Riyadh, Saudia Arabia

South America

-5:45 a.m. through 7:31 a.m. in Caracas, Venezuela

-7:41 a.m. through 10:01 a.m. in Fortaleza, Brazil (not visible from larger cities, such as Rio de Janeiro and São Paulo)

Other

-6:34 a.m. through 7 a.m. in Havana, Cuba

Path of total solar eclipse

Be careful, though, says Jay Pasachoff, Field Memorial Professor of Astronomy at Williams College.

“Since the Sun’s everyday surface is too bright to look at safely, to safely look at the partial phases people will have to make a simple ‘pinhole camera’ (merely a 3 mm or so hole in a piece of paper that is used to project the sun onto another piece of paper, and then you look at that second paper with the sun behind you) or else get special filters—almost a million times darker than ordinary sunglasses–made to be safe for observing the sun,” he writes on the college’s website. 

“The Sun is so bright that sunglasses are of no help in cutting its brightness down to a safe level,” he emphasizes. “Numbers 13 or 14 welder’s glass is safe to look through.  In any case, when using a filter, never look for more than a few seconds at a time.  Only with a pinhole camera, when you look away from the Sun at its projection rather than at the Sun, can you stare at the image for as long as you like.”

A hybrid eclipse is when the curvature of Earth’s surface causes a single eclipse to be observed as annular from some locations but total from other locations, according to NASA.

A partial eclipse is when only part of the Sun and Moon overlap. When only the Moon’s penumbral shadow strikes Earth, we see a partial eclipse of the Sun from that region. Partial eclipses are dangerous to look at because the uneclipsed part of the Sun is still very bright.

Here’s what else NASA has to say about it:

The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path. The unusual geometry is due to the curvature of Earth’s surface that brings some geographic locations into the umbra while other positions are more distant and enter the antumbral rather than umbral shadow.

In most cases, the central path begins annular, changes to total for the middle portion of the track, and reverts back to annular towards the end of the path. However, November 3 eclipse is even more unique because the central path to begins annular and ends total. Because hybrid eclipses occur near the vertex of the Moon’s umbral/antumbral shadows, the central path is typically quite narrow.

The hybrid eclipse of 2013 is visible from within a thin corridor, which traverses the North Atlantic and equatorial Africa. A partial eclipse is seen within the much broader path of the Moon’s penumbral shadow, which includes eastern North America, northern South America, southern Europe, the Middle East and Africa (Figure 5).

The path of the Moon’s shadow begins in the North Atlantic approximately 1000 km due east of Jacksonville, FL. From the central line, a 4 second annular eclipse is visible at sunrise (11:05 UT). As the shadow races forward, the narrow 4 km wide path rapidly shrinks to zero and the eclipse changes from annular to total. This all transpires within the first 15 seconds of the shadow’s trajectory. For the remainder of the track, the eclipse remains total.

Continuing on a southeast coarse, the vertex of the umbral shadow passes progressively deeper into Earth as the planet’s curvature brings the path along the surface closer to the Moon. By 11:10 UT, the track is 13 km wide and totality lasts 16 seconds. Growing quickly, the duration reaches 30 seconds by 11:18 UT.

With no landfall yet in sight, the shadow passes 500 km south of Cape Verde at 12:00 UT. On the central line, totality now lasts 1 minute 18 seconds, the Sun’s altitude is 57°, and the path width is 56 km.

Greatest eclipse occurs in the Atlantic at 12:47:36 UT, approximately 330 kilometres southwest of Liberia. At this instant, the axis of the Moon’s shadow passes closest to Earth’s centre. The maximum duration of totality is 1 minute 39 seconds, the Sun’s altitude is 71°, and the path width is 57 kilometres.

Slowly curving to the east, the track just misses Sao Tome and Principe and intercepts the coast of Gabon north of Port-Gentil in the Wonga Wongue Reserve (13:51 UT) where the central line duration is 1 minute 7 seconds and the Sun’s altitude is 46°. The Moon’s shadow crosses Gabon in 9 minutes and sweeps over the Congo in 7 more. Entering the Democratic Republic of the Congo, the path width is 36 kilometres and the duration is 48 seconds (Figure 6).

The track begins curving to the northeast as it narrows and the duration of totality decreases. By the time the umbra reaches the western border of Uganda, totality drops to 23 seconds with the Sun at 18° (14:22 UT). Sweeping over northern Kenya, the path crosses Lake Turkana where the central line duration is 14 seconds at 14:25 UT.

In its final 2 1/2 minutes, the lunar shadow races across southern Ethiopia before leaving Earth’s surface in Somalia where a 1 second total eclipse occurs at sunset.

Over the course of 3.3 hours, the Moon’s umbra travels along a path approximately 13,600 kilometres long and covers 0.09% of Earth’s surface area. Path coordinates and central line circumstances are presented in Table 3. The Universal Time (UT), the northern and southern limits, and the central line coordinates are given at five-minute intervals. The Sun’s altitude at maximum eclipse is followed by the width of the central path and the duration of totality.

    Thanks for quoting me! Did you get to see the eclipse?

    • thesevenminds November 4, 2013 at 6:49 pm

      No, I did not. I was very aware of the effects as I was putting together the post. Just in time. I was already quite happy with that!
