“Ring of Photosphere” Eclipse – June 21st

June 21st Annular Eclipse- Images and Information

Jay Pasachoff’s article about the annular eclipse in the February 2021 Astronomy Magazine


Williamstown, June 20, 2020:
tomorrow will be sad since we are unable to be in annularity for the eclipse.  It will be the first solar eclipse I will have missed in a long time.

peak is 5:30 UT in Oman, 6:30 UT in India
So in Williamstown, I’ll look for the ~1:30 am links; the 12:47 am link is for Congo, when the eclipse begins and it then takes 3/4 hour to travel to the Arabian peninsula and then another hour to travel to India.
  time in Oman: 1:30 am EDT (Williamstown)= 5:30 UTC
  time in India: 2:30 am EDT (Williamstown= 6:30 UTC

Michael Zeiler posted some links below for streaming.  (I am enjoying having his globe and his new Atlas of eclipses, both of which he advertises at the end below.)

I am consulting with scientists in Saudi Arabia, Oman, and India, advising about how best to observe the eclipse—and also asking them to make meteorological measurements (temperature/humidity/pressure) today, tomorrow, and Monday.

My own web page from the annular solar eclipse from December 26, about six months ago, from India with Jagdev Singh and Stephen Inbanathan ([email protected], American College, Madurai) there, along with Naomi Pasachoff, Rob Lucas, and Helen Robinson, is at

When does the annular phase start in local times?

12:47 am EDT is the first contact of the antumbra on Earth in the Republic of Congo. We don’t know when the live streams begin, but in Africa and the Middle East, the partial eclipse will be in progress so I expect some of the live streams to be live by then. It’s a pity you couldn’t go; a very short duration annular eclipse is of great interest.

Eastern Daylight Time – Sunday, June 21, 12:47 am
Central Daylight Time –  Saturday, June 20, 11:47 pm
Mountain Daylight Time – Saturday, June 20, 10:47 pm
Pacific Daylight Time – Saturday, June 20, 9:47 pm

* Note that “first contact”, the beginning of the partial phase, occurs just over one hour before, and “fourth contact”, the end of the partial phase occurs just over one hour after.

The Atlas of Solar Eclipses — 2020 to 2045 is an adventure guide for anyone entranced by celestial wonders and interested in seeking nature’s most stupendous sight, a total eclipse of the Sun. The atlas covers every type of solar eclipse around the world — total, annular, and partial — with beautiful and informative maps at overview, regional, and detail scales.

You can view a preview of the atlas here.

The atlas spans 56 solar eclipses from 2020 to 2045. Emphasis is given to total solar eclipses in heavily populated areas, such as the 2024 April 8 eclipse across North America, the 2027 August 2 eclipse over Europe, Africa, and the Middle East, the 2035 September 2 eclipse passing over Beijing, Pyongyang, and Tokyo, the 2044 August 23 eclipse over Canada and Montana, and the 2045 August 12 eclipse crossing North and South America. Also covered in depth is the annular solar eclipse of 2023 October 14 crossing the western United States from Oregon to Texas.

The maps give you vital information for choosing optimal locations such as the duration of total or annular eclipse at each position, sky altitude of the eclipsed Sun, and contact times of eclipse. Text accompanying the maps provide a narrative for eclipse travelers including points of interest, viewing advice, photo opportunities, visible planets and stars, and eclipse circumstances. The atlas is richly illustrated and developed in an easy-to-understand style. Also included are world maps showing every total and annular solar eclipse from 1901 to 2100.

We are pleased to announce the first ever eclipse globe produced in collaboration with Sky & Telescope magazine (skyandtelescope.org)! A nice story by J Kelly Beatty describes how this globe began and came to completion: https://skyandtelescope.org/observing/solar-eclipse-globe-for-21st-century/

This globe depicts the paths of every total solar eclipse of the 21st century, from 2001 to 2100. The eclipses shown include 68 total solar eclipses and 7 annular-total (hybrid) solar eclipses. While maps of eclipse paths have been produced since 1654, this is the first globe specifically designed to feature the paths of total solar eclipses. A globe is ideal for depicting these eclipse paths because the distortions inherent in any flat map of Earth are eliminated. Moreover, a globe accurately represents the true areal extent of totality’s path across Earth’s surface.

This globe was designed and constructed by cartographer and avid eclipse-chaser Michael Zeiler, of GreatAmericanEclipse.com, the authoritative source of detailed eclipse maps. The base map gives the physiographic view of Earth. Color tints distinguish arid regions from humid areas; lighter tints and shading depict mountainous areas. The transparent yellow paths crossing the oceans and continents mark the areas within which a total solar eclipse can be observed. Thin red lines in the centers of these paths denote where the longest local duration of totality can be enjoyed. A small red-rimmed yellow circle near the midpoint of each eclipse path shows the point of greatest eclipse (where the duration of totality is longest), along with the eclipse’s date and the maximum duration of totality in minutes and seconds.

12″ globe comes with its own clear plastic base. Truly, a vacation planner and heirloom piece for you, your children, and your grandchildren!
