Grid Layout

The western intersection of 14 and 71 (near Stoneham which is ~ 30 miles north of Brush)

• The Y = 60 line should lay on the border between Colorado and Wyoming
• Ault = 0, 31
• Peetz = 85, 57
• West Intersection of State Road 14 and State Road 71 = 55, 33
  • coordinates for Nick's Grid Calculator
  • N    40� 36.615'
  • W 103� 40.614'
• Akron = 80, 1.5

Experiments:

Colorado University Balloon Sats. Below are links to their project proposals.

• The Flying Cockroaches (Atmospheric exposure of same at high altitude)
• Project Space Monkey (Monitor atmosphere and satellite environments)
• Mega Maid (Intensity of light vs. Temperatures at various altitudes)
• Proposal 4 (Temp, Pressure, Photography)
• Project Strangelove (Radiation vs. Altitude)
• Phatsat (Atmospheric measurements, photographic platform)

University of Wyoming will also be flying several payloads (4 so far).

Notes:

The long distance Earth-Balloon-Balloon-Earth (EBBE) packet experiment has been canceled this time out.

However, we may have a second payload in the air during the flight aboard a second balloon launched from the same site. This will offer the ability to test EBBE however the range won't be much better than digipeating through a single payload.

The second payload is on the same freq (naturally) of 144.340 MHz. The callsign will be KC0JHQ-11.
