1977-038A
The only orbital data available for this flight is that for a debris object, 1977-38C, which is registered with the UN in an equatorial, circular, near-geosynchronous orbit more typical of the RHYOLITE missions.
However, independent observations in the 21st century identified two objects in 30528 x 41062 km and 29003 x 41434 km orbits typical of earlier Canyon flights. The UN-registered orbit is therefore probably incorrect.
1977-38C is in the satcat as "ATLAS AGENA R/B (2)" suggesting it may be a kick motor. Perhaps the final vehicle was heavier than the earlier ones and the Agena is in transfer orbit, with or without a third burn.
