This doesn't seem correct. If a spacecraft encounters an object where the time required to view it from Earth requires one light year would not SCET=ERT+OWLT? — Preceding unsigned comment added by 128.23.103.132 (talk) 21 November 2007
- The idea is that we want to know at what Earth time the spacecraft simultaneously observed the object. Once we receive the signal, we note the time at which it was received. Then, since it took a year for the signal to get back to Earth, we have to subtract that year from the current time to determine when the spacecraft made its observation originally.

- Just updated and expanded the article; hopefully the new version will clear up any confusion. The article could still use expert attention, though, to expand and fact-check (and to add more references). Memetics (talk) 11:37, 11 December 2013 (UTC)
