Saturday morning and afternoon an Annular Solar Eclipse / Annular Eclipse of the Sun will be visible (weather-permitting) over a wide area of the American West, as well as parts of Central America and South America. An even larger area of the United States (except the Northeastern United States), western Canada, Mexico, Central America, Caribbean area, and more than half of South America will experience a Partial Solar Eclipse / Partial Eclipse of the Sun.
NEVER LOOK DIRECTLY AT ANY SOLAR ECLIPSE / ECLIPSE OF THE SUN, UNLESS YOU HAVE THE PROPER EQUIPMENT AND PROPER TRAINING TO DO SO SAFELY; OTHERWISE EYE-SIGHT COULD BE DAMAGED PERMANENTLY !!! I
IN PARTICULAR, WITH THIS ANNULAR SOLAR ECLIPSE / ANNULAR ECLIPSE OF THE SUN, AND PARTIAL SOLAR ECLIPSE / PARTIAL ECLIPSE OF THE SUN, THERE IS NO TIME WHEN THIS ECLIPSE CAN VIEWED SAFELY WITHOUT PROPER EYE PROTECTION !!!
Live-stream Web-casts of this Annular Solar Eclipse / Annular Eclipse of the Sun will be available for people not within the path of this eclipse, inclement weather prevents direct viewing, or people and families want an absolute safe way to view this eclipse event. Internet links to Live-stream Web-casts are located near the end of this blog-post.
WHAT IS ---
A Solar Eclipse / 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 equipment and proper training to do so safely.
An Annular Solar Eclipse / Annular Eclipse of the Sun ?
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 ?
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 equipment and proper training 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 Solar Eclipse / Eclipse of the Sun) when it is safe to look directly at the eclipse, unless you have the proper equipment and proper training to do so safely!
So, there is no time during the October 14 eclipse event when it is safe to look, directly, at the eclipse, unless you have the proper equipment and proper training to do so safely!
WHERE CAN THIS ECLIPSE BE SEEN ?
The Path of Annularity for this eclipse begins in the North Pacific Ocean, where the Moon's Ant-Umbral Shadow meets the Earth. This Path of Annularity then crosses parts of nine states of the United States: Oregon, California, Idaho (small corner of southwestern part of Idaho), Nevada, Utah, Colorado, Arizona, New Mexico, and Texas.
Then, the Path of Annularity crosses the Gulf of Mexico and Mexico's Yucatan Peninsula, as well as parts of six Central American nations: Guatemala, Belize, Honduras, Nicaragua, Costa Rica, and Panama. This eclipse ends in the Atlantic Ocean, after crossing parts of the South American nations of Colombia and Brazil.
For a wide area, on both sides of the Path of Annularity, a Partial Solar Eclipse / Partial Eclipse of the Sun will be visible.
Of course, as with all astronomical events, visibility is weather-permitting
WHEN CAN THIS ECLIPSE BE SEEN ?
This eclipse will occur during the mid-day hours of Saturday, 2023 October 14 ---
(EDT = Eastern Daylight Saving Time / UTC = Coordinated Universal Time)
> First location where partial eclipse begins: 11:03:50 a.m. EDT / 15:03:50 UTC
> First location where full annular eclipse begins: 12:10:11 p.m. EDT / 16:10:11 UTC
> Primary Moon Phase: New Moon – Lunation #1247: 1:55 p.m. EDT / 17:55 UTC
> Greatest eclipse (off the coast of Nicaragua): 1:59:32 p.m. EDT / 17:59:32 UTC
> Last location where full annular eclipse ends: 3:49:01 p.m. EDT / 19:49:01 UTC
> Last location where partial eclipse ends: 4:55:16 p.m. EDT / 20:55:16 UTC
For the Annular Solar Eclipse / Annular Eclipse of the Sun, the time of Annularity or “Ring-of-Fire” will reach a maximum time of 5 minutes and 17 seconds. The Path of Annularity will be 116 statute miles / 186.683904 kilometers wide.
At the most, the Moon will cover 90 per-cent of the solar disk.
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 October 14 eclipse precedes a Partial Lunar Eclipse / Partial Eclipse of the Moon on October 28, which will primarily be visible in Earth's Eastern Hemisphere.
How to Determine Sunrise and Sunset times for your location ---
The time this eclipse can be seen varies for each location on Earth, located along the eclipse path. Of course, it can only be seen while the Sun is above the Horizon for any particular location.
Check your local newspaper or television weather reports, or weather app on your cellular telephone;
For those who can receive the NOAA Weather Radio station in their area, often the National Weather Service provides Sunrise and Sunset times during their daily local, “Climate Summary” report;
Submit your Zip-Code or city name to one of two Internet web-sites:
a) U.S. Naval Observatory – Link >>> https://aa.usno.navy.mil/data/RS_OneDay
b) Heavens-Above.com – Link >>> https://www.heavens-above.com/sun.aspx
HOW TO SAFELY VIEW ANY SOLAR ECLIPSE / ECLIPSE OF THE SUN ---
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..
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.
Solar Pinhole Viewing Box - Create a Solar Pinhole Viewing Box, as displayed and described at the beginning of this blog-post.
“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.
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 !
