SEOUL, Nov 6 - South Korea's foreign exchange authorities were spotted buying dollars on Friday to check the won's <KRW=> gains, traders said.
"The authorities absorbed dollar offers about 10 minutes before the market closed to manage the won's closing price," said a local bank dealer.
The local currency was quoted at 1,166.4/8.4 per dollar as of 0600 GMT, compared with Thursday's domestic close <KRW=KFTC> of 1,179.8.
Earlier, the won strengthened to as firm as 1,165.9, the strongest since Oct. 20. (Reporting by Cheon Jong-woo and Lee Soo-jung; Editing by Jonathan Hopfner)
