Annular Solar Eclipse- full details – Sunday 26th February 2017 (and deciphering scientific diagram)

As you know we’ve already had the penumbral Lunar Eclipse a week and a half ago, and the counterpart ..  the Solar Eclipse will be occurring in a few days(Eclipses always occur in pairs, separated by 2 weeks).

I’ve downloaded the detailed Eclipse-diagram of visibility / location data from NASA website (Eclipse diagram/data (c) Fred Espenak – link at the bottom).

Annular Solar Eclipse is when the Moon eclipses the Sun (as viewed from Earth by us)..  but moon does not fully cover the Sun.  So at the greatest Eclipse, the Moon covers the central disc of the Sun..but there is a ring of Sun showing around it – the so called Ring of Fire.  During the progress of this Eclipse (while its getting into the `greatest Eclipse’ position slowly..and also afterwards, there is also an effect called the Diamond Ring .. that can be seen on the edges of the moon..  (called Baily’s Beads- caused by light shining through valleys on the Moon’s surface).

 

 

 

Annular Solar Eclipse (26Feb2017) Details:

How long is this Eclipse?

Important point to remember is that, at any one location on the Earth, the actual Solar Eclipse is only visible for few minutes at most.   BUT it will be seen at different parts of the world at various times..  and at each part ..for slightly different duration.

Maximum Eclipse duration:

This happens around 13:16hrs UT,  and for a duration of  1 min 22 seconds..  and will be visible only for those at South pacific ocean…off the coast of Chile!  (Note: Although the Sun is Eclipsed for the longest at this point, it is not covered the most amount at this point.  That happens later..but for a shorter duration).

Greatest Eclipse and its duration:

This is when the largest amount of the Sun is covered by the Moon..  and  takes place at 14:53 hrs  (Universal Time), and will be visible for 44 seconds, from a point in South Atlantic Ocean.   (note: sometimes the Greatest Eclipse happens for lesser duration).

Penumbral start & end of Eclipse:

There are two types of shadows formed by the Moon when it comes in front of the Sun..  ie the shadow that Earth Passes through.  Umbral shadow is the darkest part, where from under it, we see nothing of the Sun.  Penumbral shadow is a more lighter part, and we will see the Sun through it..

  • P1 : The Penumbral part of the eclipse will be first visible at  12:10hrs   UT  (seen from South pacific ocean…off the coast of Chile as Sun rises for them locally).
  • P4:  The penumbral part of the Eclipse will be last visible at 17:36 hrs UT (seen from Africa – Zambia/  Botswana – before night falls locally there)

The Umbral  Eclipse data:

This is when the Sun is actually visibly blocked by a dark disc (Moon coming between us and the Sun).  In scientific  notations, we give this 4 sets of readings..  when it first starts (first contact/ start of Umbral Eclipse; 2nd contact;  when Eclipse begins to end; when final umbral eclipse fully ends.

  • U1 : 13:15 hrs UT
  • U2 : 13:16 hrs UT
  • Greatest Eclipse :  14:53 hrs UT
  • U3 : 16:30 hrs UT
  • U4 : 16:31 hrs UT

Here are the NASA diagrams created/provided  by Fred Espanak, where all this data has been taken from:

I’ll be adding a general astrological chart (drawn for the moment of greatest Eclipse and it’s location) later.  (going to take a bit of work) .

ps.  If you are interested in doing Esoteric / ritual magical work / energy work, during the Eclipses, I have written a workbook (probably the world’s first book on Eclipse Magic).  here’s the link to buying it.

Full data for Solar & Lunar Eclipses in 2012

Hi all,  I thought some actual data is very useful for those of you who just want to observe, or do esoteric / magical work.

All times are `Universal Time (UT) which is for all intents equivalent to GMT.  Universal Time is based on the rotation of Earth on its axis with respect to the Stars!

Some explanations  (types of eclipses):

  • Annular – when the Moon blocks out the Sun and a ring of the Sun can be seen around it.
  • Partial – when only part of the Sun or moon is blocked.
  • Penumbral eclipse:  This is difficult to spot easily, as the object (moon) just gently goes a bit darker or redish.

Annular Solar Eclipse:  20th May 2012

Greatest Eclipse at  23:52 hrs UT      (Duration: 5 min 46 sec).

P1-  20:56 hrs;      P4- 02:49 hrs.

U1 – 22:06 hrs;   U2 – 22:11 hrs;   U3- 01:33 hrs;  U4- 01:39hrs.

Total Solar Eclipse:  13th Nov’12

Greatest Eclipse at 22:11 hrs   (duration: 4min 02 sec).

P1  19:37 hrs;       P2- 21:43;      P3- 22:39;        P4- 00:45;

U1- 20:35;            U2- 20:37;        U3-23:46;        U4-23:48 hrs;

Partial Lunar Eclipse:  4th June’12

Greatest Eclipse at 11:04 hrs   ( 2 hrs 07 min).

P1- 8.48hrs;       U1- 9;59 hrs;       U4- 12:06 hrs;     P4- 13:18 hrs;

Penumbral Lunar Eclipse:  28th Nov’12

Greatest eclipse at 14:34 hrs    (4 hrs 35min).

P1- 12:14 hrs;         P4- 16:50hrs.

Explanation of P1, P2, U1 etc..    Above diagram shows what happens at eclipses, graphically and pictorially. Large light sources (such as the Sun) create 2 types of shadows – the lighter shadow called Penumbra, and the true full shadow (no light) called Umbra. When Earth passes through the shadow, it must go through penumbra, then into Umbra, then  penumbra and finally out of it.  Each of these entry & exit stages have been designated a notation in science. P1 is the time when the Earth begins to enter the outer shadow. U1 is when it enters the full shadow. U2 is when it is fully inside the full shadow, and U3 is when it starts to leave it.  This means the time between U2 & U3 is when it is fully in the dark – `Greatest Eclipse’ (and the duration of this is given in tables above).

Sometimes the stellar object may not pass into the full shadow (umbra). It may skirt through only the penumbra. This happens on the Lunar eclipse of 28th Nov’12, when the moon just passes through Earth’s penumbral shadow only.
