Annular Solar Eclipse Early Thur. w/Web-Casts

NO ANNULAR SOLAR ECLIPSE / ANNULAR ECLIPSE OF THE SUN OR THE PARTIAL PHASES OF ANY OTHER SOLAR ECLIPSE / ECLIPSE OF THE SUN IS SAFE TO LOOK AT DIRECTLY, UNLESS YOU HAVE THE PROPER TRAINING AND PROPER EQUIPMENT TO DO SO SAFELY. OTHERWISE EYE-SIGHT COULD BE DAMAGED PERMANENTLY !!! This graphic shows one way to safely view an Annular Solar Eclipse / Annular Eclipse of the Sun or the partial phases of any other Solar Eclipse / Eclipse of the Sun by building a Solar Pinhole Viewing Box (a.k.a. Pinhole Camera) as shown above. After building this box, you must turn your back to the Sun and allow the light from the Sun to go through the pinhole and shine on a white piece of paper on the other end of the box (NEVER LOOK THROUGH THE PINHOLE AT THE SUN!).

Early Thursday, a somewhat unusual Annular Solar Eclipse / Annular Eclipse of the Sun will be visible in parts of Canada, Russia, and Greenland, with a Partial Solar Eclipse / Partial Eclipse of the Sun viewable in other parts of Canada, eastern and mid-western U.S., Alaska, Europe, and parts of Asia and Africa. The Annular Solar Eclipse / Annular Eclipse of the Sun can also be viewed on live-stream web-casts.

NEVER LOOK DIRECTLY AT ANY SOLAR ECLIPSE / ECLIPSE OF THE SUN, UNLESS YOU HAVE THE PROPER TRAINING AND PROPER EQUIPMENT TO DO SO SAFELY; OTHERWISE EYE-SIGHT COULD BE DAMAGED PERMANENTLY !!!

Internet links to live-stream web-casts of this eclipse are located near the end of this blog-post.

WHERE CAN THIS ECLIPSE BE SEEN ?

Depending on your location, during, or shortly after, sunrise on Thursday morning (2021 June 10), an Annular Solar Eclipse / Annular Eclipse of the Sun will be visible in a narrow band (known as the Path of Annularity) starting in portions of eastern Canada (parts of the provinces of Ontario and Quebec, and the territory of Nunavut), northwestern Greenland, the North Pole and ending in Russia (part of northeastern Siberia). People in other parts of Canada, eastern and mid-western U.S., Alaska, and Europe as well as parts of the Caribbean, northern Asia, and northern Africa will see a Partial Solar Eclipse / Partial Eclipse of the Sun.

Of course, as with all astronomical events, visibility is weather-permitting 

WHEN CAN THIS ECLIPSE BE SEEN ?

This eclipse will occur in the early morning hours of Thursday, 2021 June 10 ---

(EDT = Eastern Daylight Saving Time / UTC = Coordinated Universal Time)

• First location where partial eclipse begins: 4:12:20.2 a.m. EDT / 8:12:20.2 UTC

• First location where full annular eclipse begins: 5:49:47.7 a.m. EDT / 9:49:47.7 UTC

• Greatest eclipse (local Noon, northern Greenland): 6:41:56.3 a.m. EDT / 10:41:56.3 UTC

• Primary Moon Phase: New Moon – Lunation #1218: 6:52 a.m. EDT / 10:52 UTC

• Last location where full annular eclipse ends: 7:33:50.8 a.m. EDT / 11:33:50.8 UTC

• Last location where partial eclipse ends: 9:11:21.4 a.m. EDT / 13:11:21.4 UTC

Each point where the Annular Solar Eclipse / Annular Eclipse of the Sun occurs, the time of Annularity or “Ring-of-Fire” does not exceed 3 minutes and 51 seconds.

The time this eclipse can be seen varies for each location on Earth. Of course, it can only be seen after the Sun rises, and in many locations the eclipse is well under-way by sunrise.

To find out when the Sun rises in your locale, you can submit your zip-code or city name to the web-site https://www.heavens-above.com and select the Sun rise and set page. For those who can receive the NOAA Weather Radio station in their area, often they provide sunrise and sunset times during their daily local, “Climate Summary” report. Newspaper and television weather reports sometimes also give the local sunrise and sunset times.

A Solar Eclipse / Eclipse of the Sun always comes a couple weeks before or a couple weeks after a Lunar Eclipse / Eclipse of the Moon. The June 10 eclipse follows the first eclipse of 2021, a Total Lunar Eclipse / Total Eclipse of the Moon on May 26.

WHAT IS ---

An Annular Solar Eclipse / Annular Eclipse of the Sun ?

A Partial Solar Eclipse / Partial Eclipse of the Sun ?

A Solar Eclipse / Eclipse of the Sun occurs when the Moon comes directly between the Sun and the Earth and part or all of the lunar shadow falls on a portion of our planet. This is the type of eclipse that is dangerous to eye-sight to view directly, unless you have the proper training and proper equipment to do so safely.

An Annular Solar Eclipse / Annular Eclipse of the Sun is somewhat similar to a Total Solar Eclipse / Total Eclipse of the Sun. However, unlike a Total Solar Eclipse / Total Eclipse of the Sun, the Sun is never completely covered by the Moon during an Annular Solar Eclipse / Annular Eclipse of the Sun.

During an Annular Solar Eclipse / Annular Eclipse of the Sun, the Moon blocks-out the vast majority of the Sun, except for the extremely bright edge of the solar disk. Hence, this type of eclipse is often referred to as a “Ring-of-Fire” Solar Eclipse, as the bright edge appears as a ring-of-fire around the dark Moon.

The reason an Annular Solar Eclipse / Annular Eclipse of the Sun does not completely block-out the Sun's light, as does a Total Solar Eclipse / Total Eclipse of the Sun, is because during an Annular Solar Eclipse / Annular Eclipse of the Sun the Moon is farther from Earth than normal and appears a little smaller as viewed from Earth. Hence, the Moon is too far, and appears too small, to block-out the entire solar disk.

A Partial Solar Eclipse / Partial Eclipse of the Sun occurs when only part of the Sun is blocked by the Moon. This is also true during the partial phases of a Total, Annular, or Hybrid Solar Eclipse / Total, Annular, or Hybrid Eclipse of the Sun. Usually, more of the Sun is still visible than during an Annular Solar Eclipse / Annular Eclipse of the Sun.

There is no time during an Annular Solar Eclipse / Annular Eclipse of the Sun when it is safe to look directly at the eclipse, unless you have the proper training and proper equipment to do so safely!

Also, there is no time during a Partial Solar Eclipse / Partial Eclipse of the Sun (or during the partial phases of any other Solar Eclipse / Eclipse of the Sun) when it is safe to look directly at the eclipse, unless you have the proper training and proper equipment to do so safely!

So, there is no time during the June 10 eclipse event when it is safe to look, directly, at the eclipse, unless you have the proper training and proper equipment to do so safely!

HOW TO SAFELY VIEW ANY SOLAR ECLIPSE / ECLIPSE OF THE SUN ---

1. Internet - Watch the eclipse on an Internet, Live-Stream Web-Cast (Internet links to web-casts near the end of this blog-post). Of course, people outside of the path of an eclipse can also watch the eclipse on an Internet, Live-Stream Web-Cast, as well as people within the eclipse path where clouds obscure the view..

2. Public Observing Events - Sometimes educational events for eclipse viewing are sponsored by a local planetarium or science museum, astronomical observatory, science department of a local college or high school, amateur astronomy club, or local library.

3. Solar Pinhole Viewing Box - Create a Solar Pinhole Viewing Box, as displayed and described at the beginning of this blog-post.

4. “Solar Eclipse Glasses” - For a few dollars you can purchase Solar Eclipse Glasses. However, only use such glasses that are specifically labeled for solar eclipse viewing, preferably approved by the American Astronomical Society (to ensure you do not purchase fake eclipse glasses). Special Note: Solar Eclipse Glasses are very fragile and must be handled gently. Also, before each use during an eclipse, check the glasses by looking through the glasses at a lit light bulb; if you find any holes or tears in the glasses, that pair of glasses could damage your eye-sight during eclipse viewing and should be discarded.

5. Shade Rating Number 14 Welder's Glass – Shade Rating Number 14 Welder's Glass (and only Welder's Glass Rated at Shade Number 14, the strongest shade available) can be used for safe eclipse viewing, but may be uncomfortable to some because the Sun still appears very bright through this glass.

THESE ARE THE ONLY SAFE WAYS TO VIEW ANY SOLAR ECLIPSE / ECLIPSE OF THE SUN !
