Notes

Impact times are Earth received times, approximately 1.3 seconds later than real time on the Moon.

Listed coordinates are derived from the Manned Space Flight Network tracking data referenced to a mean
spherical surface and may differ by several km from coordinates based on surface features.

The SIVB is the Saturn upper stage which was targeted towards the Moon after separation from Apollo.

The Apollo 11 SIVB was injected into heliocentric orbit, the Apollo 12 SIVB into Earth orbit.

The Apollo 11 and 16 LM's were jettisoned into (temporary) lunar orbits.
The Apollo 13 LM re-entered Earth's atmosphere on 17 April 1970.

*A malfunction resulted in premature loss of tracking data for the Apollo 16 SIVB.
Time, location, and impact energy are estimates based on interpretation of seismic data.
Uncertainty in the Apollo 16 impact time is about 4 seconds.
Uncertainty in the Apollo 16 impact location is about 0.7 deg. latitude, 0.3 deg. longitude.
(The impact location estimated based on tracking prior to signal loss is 2.24 N, 24.49 W)

Most data from Toksoz et al., 1974
