UPDATE:
The U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) staff have been coordinating with the appropriate FAA offices in support of this deployment and have an approved COA (Certificate of Authorization aka waiver). However, they are delaying the June tethered balloon operations as they are reviewing the flight safety plans again with the local FAA Safety Team. When they have a new start date, they will notify the local flight community with a NOTAM seven days prior to start along with other local notifications.
Heads up! This will be NOTAMed, but raising awareness here. Starting June 1st and continuing periodically through the monsoon season, two tethered research balloons (24ft in diameter) will launch up to 4,200 feet AGL. The site is SW of the KDVT delta, outside KDVT and KGEU’s deltas and under the Bravo shelf.
