When the Apollo missions went to the moon, reports of flashes were made by multiple astronauts. Upon return, no retinal defects were seen. It was theorized that cosmic rays may have triggered the retina or visual cortex - the phenomena happening when outside the earth's electromagnetic shield.

For Apollo 16 & 17, an experiment was devised, astronauts would wear a box with x-ray film lining the sides for about an hour when off-duty. The boxes recorded 16 cosmic ray penetrations. Two of them correlated to time the astronauts recorded seeing a flash.

We haven't heard if the Artemis II crew reported any flashes at the time of this posting.

This Saturday, Oklahoma will experience a partial annular eclipse.

What is an annular eclipse?

An annular eclipse is when the moon passes between the sun and the Earth while it is at it's farthest point away from the Earth. Because the moon is far away from the sun, it appears smaller than usual and does not completely block out the sun. This creates a "ring" effect in the sky.

Stay safe when viewing the partial eclipse by wearing proper eye protection!

How do you stay safe during the partial solar eclipse on October 14, 2023?

Use Solar Eclipse glasses, which are specialized filters that are designed to protect your eyes when viewing a partial or total solar eclipse. They are MUCH different than sunglasses and are specifically designed to protect your eyes from permanent vision loss and damage from viewing an eclipse.

Safety tips according to NASA:
-use only solar eclipse glasses when viewing an eclipse
-make sure that your solar eclipse glasses are compliant with "ISO 12312-2" (the international safety standard)
-inspect your glasses for any holes/tears/scratches; if you see any, throw them away and get new ones!
-do not use solar eclipse glasses with cameras, telescopes or binoculars; these require specific solar filters
