That was the ANZ DC10 / Gordon Vette incident discussed above:

https://en.wikipedia.org/wiki/Cessna_188_Pacific_rescue

Vette was able to use the setting sun to gain an approximate position of the Cessna. He instructed the Cessna to point directly at the setting sun. He did the same, and noted the difference in heading between the aircraft as four degrees. After making an allowance for the differing altitudes of the aircraft, the difference in sunset times between the aircraft and Norfolk Island was also noted. This data allowed the crew to calculate that the Cessna must be south west of the DC-10 by about 400 nautical miles. About 25 minutes after turning in that direction, contact on short range VHF radio was established.
