Original Announcement: 

Update 7/26/2022 0600: Updated 327 Heavy payload plans to correct typo.  Updated both 326 plans to correct the launch time to 0700.

This will be a launch of two 3000g Balloons for the Ball Internship BIRST program and the Summer Colorado Space Grant Consortium Colleges. 

In memory of the passing of EOSS Member John Blakely, The top beacon of the first balloon KC0D-14, will transmit "EOSS BALLOON In Memory of K0JWB John Blakely SK" at the end of each position packet.  SK signifies that an Amateur Radio operator is a Silent Key since their transmissions have ended.

 If cloud cover precludes the launch of heavy balloons, the payloads will be launched on three exempt 1500g balloons.
