INITIALIZING BALLOON-TRACK GLOBAL SCAN...
◈ WHAT IS BALLOON-TRACK?
BALLOON-TRACK is a live radiosonde proximity scanner powered by the SondeHub global network — a community-operated system of ground receivers that track weather balloons launched by meteorological agencies worldwide.
Weather balloons — officially called radiosondes — are launched twice daily from hundreds of sites globally. They ascend to 100,000+ ft, transmitting atmospheric data, before descending by parachute.
Radiosondes are among the most common sources of UAP misidentification. A slowly rising, bright spherical object at high altitude — especially at dawn or dusk when sunlight catches the balloon while the ground is dark — is frequently reported as an unidentified aerial phenomenon.
BALLOON-TRACK automatically checks every sighting report against live radiosonde data and flags any balloon that was near the observer at the time of the sighting.

◈ HOW IT APPEARS IN YOUR REPORTS
When you submit a UAP Sighting, Abduction/Encounter, or Observation Report, the system automatically:
① Queries SondeHub for all radiosondes within 500 km of your location at the time of your sighting
② Finds the balloon frame closest in time to your sighting event
③ Calculates each balloon distance, elevation angle, and bearing from your position
④ Assigns a misidentification risk score — HIGH if a balloon was ascending, above 20 degrees elevation, within 200 km, and moving slowly
⑤ Appends a full BALLOON-TRACK PROXIMITY REPORT to your node record alongside the satellite, flight, weather, and star chart data
A HIGH RISK flag means a weather balloon was in the right place at the right time to explain the sighting. A LOW RISK result strengthens the credibility of your report.

● GREEN = ASCENDING — rising, most visible, highest misid risk
● RED = DESCENDING — falling under parachute
● YELLOW = FLOATING — near burst altitude, drifting
○ GREY = UNKNOWN — signal intermittent
⚠ ORANGE RING = HIGH misidentification risk
