Tomorrow, Saturday, is a big day for followers of the much expected annular eclipse. The eclipse for Martha's Vineyard residents will essentially be partial, a non event and almost unnoticeable. A short time after 1 p.m. only 20 per cent of the sun will be blocked by the moon. That will be difficult to detect. Eye safety is really the biggest issue associated with the eclipse. Do not, under any circumstances look up at the brilliant shining sun anytime. The possibility of permanent eye damage is real.

Some may still have safe eclipse glasses left over from the partial annular eclipse of Thursday, June 10, 2021. That eclipse occurred after sunrise and was fairly easy to see. The sun was low near the horizon and partially obscured by fog and thick clouds.

Tomorrow's event is potentially more dangerous, since the sun will be high in the sky and here there is not much of the eclipse to see.

The best show will be on the Western end of the country and totality will be a narrow strip of land extending from Oregon down though the midwest and across Texas.
