The Bulgarian national flag was first flown in Antarctica by meteorologist Tsoncho Chapanov on February 3, 1967. 

He was included in the 12th Soviet Antarctic Expedition as part of an international team that also included scientists from Czechoslovakia and the USA.

Chapanov departed on January 19, 1967 by plane from Leningrad, traveling through India and Indonesia to Australia, from where he arrived at the Soviet polar base Mirny aboard the icebreaker Ob. 

Being the main Soviet center for Antarctic research, the Mirny Observatory was a large settlement with many houses, laboratories, workshops, and other facilities, located on the Antarctic Circle, on the shore of the Davis Sea, near the Shackleton Glacier.
