OMSI Star Party - Partial Solar Eclipse - 5pm-7:30pm at OMSI Parking Lot
While the Annular Eclipse will only be visible within the maps below, it will be visible from Portland as a 80% Partial Eclipse.

For More Information on Viewing Safely
http://eclipse.gsfc.nasa.gov/SEhelp/safety.html

WARNING: ANY TYPE OF SOLAR ECLIPSE IS NOT SAFE TO VIEW WITHOUT ADEQUATE EYE PROTECTION
Sunglasses DO NOT provide adequate eye protection
 Viewing the Sun indirectly, by projecting its image onto a screen, is far safer.

You can make a simple projector with a pinhole in a sheet of cardboard and projecting the image on a sheet of white paper

or using a cardboard box to project the sun.

Welder's Glass - Welding glass is used to protect welders from eye damage. Welder's glass is numbered from 1 to 14 with 14 being the darkest. It is only number 14 glass that is dark enough for solar viewing! And NO STACKING! A pair of number 7's or a 10 and a 4 together DO NOT have the same protection as a single piece of number 14.

Approximate Times will vary by a minute or so depending on location

Start of partial eclipse : 5:10pm

Maximum eclipse: 6:28pm
The sun will only be 20 degrees above the horizon
Maximum along center line is approximately 4 1/2 minutes.

End of partial eclipse: 7:36pm

Sunset 8:40pm
Moonset 8:45pm

Annular eclipses, so named because of the ring shape of the sun, are fun to watch
however they lack the complete transformation seen during a total solar eclipse.
