What we're about

The Eugene Astronomical Society is a group of amateur astronomers dedicated to observing the sky and learning about the Universe, and sharing that understanding and appreciation of astronomy with students and the general public. The club meets each month, typically the third Thursday, and offers a strong telescope lending program.

SUN-day in the Park

Alton Baker park

This Sunday at noon, weather permitting, join us for SUN-day in the park. Several of our club members have special telescopes and filters that allow safe viewing of our nearest star -- the Sun -- and we'll be sharing the view with the public. Our previous events were great successes, so we plan to do this every Sunday for as long as the weather holds. Come see solar prominences, filaments, sunspots, spicules, faculae, and various other difficult to pronounce but beautiful features visible in our scopes. Some days the Sun is quiet and there's not much to see, but other days it can be quite dramatic. Drop by on SUN-days and see what's happening up there. We'll gather near the scale model Sun to the south of the duck pond in Alton Baker Park, starting at noon. Solar viewing must be done with the proper equipment! Don't try viewing the Sun unless you have the right equipment for it and know how to use it safely. Come to our SUN-days and view it safely with us.

First Quarter Friday - Star Party

College Hill Reservoir

The Eugene Astronomical Society holds monthly star parties on Fridays closest to the moon's first quarter (First Quarter Fridays), and occasionally on additional dates during the clear summer months. We gather just before dusk and stay as long as there is interest. Everyone is welcome to come, and we usually have many different types of telescopes set up for viewing (some invented by our members!) First Quarter Fridays are held at College Hill Reservoir, on Lawrence street between 23rd and 25th in Eugene. Locations of other star parties are announced with the star parties themselves. Star Party Dos and Don'ts Dress warmly. Nights can get chilly even in summer. Preserve your night vision and everyone else's. It takes up to 20 minutes for eyes to adapt to the dark. A single burst of bright light can ruin that for everyone. If you carry a flashlight, use the dimmest light you can, and cover the lens with red filter film. (Red light isn't quite as damaging to night vision as white light.) Automotive brake-light repair tape works well. You might need several layers. Remember that once your eyes adapt to the dark, it doesn't take much light to see your way around--or to ruin your night vision. Cell phone screens are way too bright to use at star parties. Please go a long ways from the group before using your cell phone. Star parties tend to be informal, with several telescopes set up more or less at random and people milling around between them to look at different objects through different scopes. Don't be shy; come on up and say "Hi" and have a look. If there's a line behind a telescope, it's okay to ask the person operating it what that scope is pointed at before you get in line. Ask questions! Amateur astronomers love to share what we've learned about the night sky. Children are welcome, but small ones tend to grab for the eyepiece, often with sticky fingers. Fingerprints can ruin an eyepiece, and eyepieces can be very expensive. Before you allow your child to look through a telescope, explain to them how to clasp their hands behind their backs and simply look into the eyepiece, not touching any part of the telescope. Practice this at home with a pair of binoculars or a toilet-paper tube. If they cannot follow this procedure, please do not bring them to a star party. Please leave your dogs at home. In the dark, they could cause accidents if they get underfoot. Pets are not allowed at any time at the Reservoir because of water purity concerns. Star parties are always "weather permitting." Check the sky before you set out to spare yourself a trip if the sky is cloudy.
