Special Online Auction

Bid on items from anywhere!

This year, ACES is holding its first online auction. Due to some chilly weather during Harvest Party this year, we've decided to put unsold items from our silent auction up online!

Astronomy Night | November

ACES invites you to Hallam Lake this Fall to look up and learn about the night sky! Each evening starts with a 15-minute lesson covering basic astronomy concepts such as life-cycle of a star, reasons for meteor showers, what planets might be visible, or how phases of the moon work. After the mini lecture we will gather outside for the stargazing portion of the evening. Aspen High School Astronomy Club member Ricky Woycik will be on-hand to guide you through the phenomena of the mountain night sky.
ACES Astronomy Nights are monthly gatherings on Mondays throughout the year to appreciate the spectacle of the night sky. Join us for one evening or all of them - you will see and learn something different each time. We will have our Summer Schedule with even more Astronomy Nights available by April 2017.
Please RSVP - each evening is limited to 50 people.
 
November 13, 7:30pm – Phases of the Moon
How is it that we see a different amount of the moon on any given night? What is our moon and why is it there? We’ll dispel some myths and learn new facts about our moon. If we are lucky we’ll even see the full Supermoon tonight!
 
Aspen High School (AHS) student Ricky Wojcik is a promising local astronomer whose love for stars and the cosmos was ignited by the AHS Astronomy Club. Travis Moore, the AHS science teacher who started the club, has inspired many of young minds to look beyond our planet and gain a greater appreciation for our place in the Universe. Ricky loves looking at the stars and learning all there is about Astronomy - from attending numerous physics lectures and following astronomical discoveries on the web to bombarding other astronomers with questions.... All that is in addition to schoolwork, Nordic ski racing career and well, just being a regular high-school kid.
In Ricky’s words: “Aspen’s night sky is very special and Hallam Lake offers an incredible spot to look at the beautiful stars and space that surrounds us.”

Audubon Christmas Bird Count

ACES invites you on Sunday, December 17, 2017 to help count birds in the Aspen area during the 118th Audubon Christmas Bird Count (CBC), the longest-running citizen science survey in the world. Birders of all experience levels are welcome and encouraged to participate in this important census that has helped assess the health of bird populations and guided conservation action since 1900. Across the Western Hemisphere, over 50,000 people count birds during local count events, many making the adventure of winter birding a seasonal tradition. Birders will meet at Hallam Lake before heading out to count in the Aspen area. Other ways to participate in addition to the count day, are: feeder watching, owling, and count-week observations.

For more CBC experience, join the mid-valley Audubon Christmas Bird Count hosted by Roaring Fork Audubon on Saturday, December 16, 2017. Contact Tom McConnell for more information at 970-379-7356 or immac@rof.net.

View our summary of the 2016 CBC here, and get into the swing of local winter birding at our Birding with ACES class on December 5th, January 2nd, and the first Tuesday of the month throughout the winter season. We hope you'll join ACES bird guide Rebecca Weiss for this important citizen science event! 

This event is free and open to the public. Please RSVP below.
