Barbados Will Experience Partial Solar Eclipse | Protect Your Eyes

The BU household extends a big thank you to Chris Halsall for the submission which seeks to educate the public about the partial solar eclipse Barbados will experience tomorrow. Take heed!David, Barbados Underground

While a once-in-a-life-time event for the western northern hemisphere (totality across most of the United States of America (the next such event is not expected for something like 100 years), solar eclipses can actually be quite dangerous for those who don’t understand the risks to their eyes.

It is ***never*** safe to look directly at the sun with your eyes.  Interestingly, this is even more true during a partial solar eclipse, which we here in Barbados will experience for approximately 2 hours and 22 minutes starting at 14:33 (2:33PM), with a maximum occlusion of 73% at 15:49, and ending at 16:56.  Please see link reference #1 below.

The reason for this is since the sun will be partially occluded, our eyes’ pupils (the biological equivalent of a camera’s aperture) will close less.  But, the intensity of the light from the part of the sun still visible will still be as intense.  While it might not hurt as much to look, the eyes’ retina still risks being burnt out.  Permanently!

I have heard people say that they plan to look at the eclipse with really dark sunglasses.  Not safe!  I heard from other person close to me that they looked at an eclipse through a CD.  Even less safe; they were very lucky it was heavily overcast at the time.

In fact, even welding goggles are not safe to view an eclipse through unless the shade rating is greater than 11; very (very!) few are.  Please see link reference #2 below.

There is only one way to view the eclipse safely with the human eye without properly rated filters: a “Pinhole Projection”.  Please see link reference #3 below.

A wonderful opportunity to teach people about celestial mechanics (and, for that matter, optics).  And in addition many people find solar eclipses quite spiritually moving.

I’m really looking forward to the event, and plan to go outside with my pinhole box to observe the crescent, and the very unusual dusk during the afternoon.  I also deeply hope that no one damages their vision for the rest of their lives because of a silly mistake made during this event.

    I hope a wide enough public awareness campaign has been launched. There are countless people, including our CARIFESTA guests who may not be easily reached by the media and TV about the damage of staring into the eclipse. Who is distributing filter film (glasses)?

    I will dance on the meadow during the eclipse, burning chicken and chanting the name of Godess Bim.

    The Christian pastors on this island abandoned the population long ago for the sake of Mercedes and BMW.

    Nothing gets my adrenalin flowing like the wonderful spectacles of nature. The total eclipse is a hard one to top. Also , I find it extremely intellectually stimulating of the exact prediction of these events. No easy task given, the complexity of celestial mechanics. Big shout out to intellectual giants like, Copernicus, Brahe, Kelper, Gallaleo, Langrange and Newton.

    Agree with you, it makes on give even more respect to the scientist you mentioned given the mechanical – no computers- of that time.

    ++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    How about to the “Big Boss Scientists”, who conceptualised, designed, built ,and maintained the whole thing …. from scratch?

    …any respect there…?

    See if you can influence PLT in the matter…. 🙂

    Much respect due to mother nature for its unique precision and timing as it leaves it signature footprints among us for all of mankind to see a greater than great reminder as to who is really incharge

    The area I am currently in ( western USA) will have close to 100% coverage, only have my prescription sunglasses so will stay indoors until it rolls over. Incidentally it was sunny earlier now it has disappeared behind the clouds

    It is recommended to view the eclipse through welder’s no 14 glass or two no. 7 welder’s glass.

    Looking around Barbados today the vast majority didn’t seem to excited by the prospect of witnessing the partial eclipse. Maybe it explains why STEM has not take root.

    To be honest the 71% partial eclipse here in New York was nothing to write home about.
    You had to be some place with the total eclipse or watch NASA TV as you did.

    Consider The Signs Of The Times

    Remember that The Solar Eclipse Went Across America, not even Canada and the last time that happened in the USA Alone was in the year 1776, the Year of Declaration of American Independence.

    If we can read the Signs of the times this may well be a Renewal of that Spirit and by no means a Coincidence that President Trump gave his first Commander In Chief Speech on that Same Day that the Solar Eclipse Crossed America!

    Genesis 1:14-19King James Version (KJV)
    14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:

    Luke 21:25-28King James Version (KJV)
    25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
