Oops, here is the info on the Colorado Balloon this Saturday:

... around ~630 AM MDT (1230UTC) this Saturday (April 10th), ... going to be attempting to stream the launch and recovery live on the internet.... ... carrying 24 lbs of [student] payloads... from Windsor, CO at 0700 MDT. The balloon will ascend to ~102,000 feet, burst, and the payload will then descend under parachute. The current prediction has the landing at ~0915 MDT near the Colorado/Nebraska border, ~90 miles downrange from launch.

The balloon will be carrying an APRS beacon, callsign AE0SS-11, on 144.340 MHz , as well as a CW DF Beacon on 147.555 MHz. At apogee, both beacons should be copyable throughout Colorado and well into surrounding states.
