NEW YORK, June 12 (Reuters) - U.S. Treasuries prices rose on Friday on follow-through buying from Thursday's relief rally after the market underwrote and distributed another $65 billion of securities with relative ease.

The Treasury sold three-, 10- and 30-year securities in three auctions this week, concluding with the 30-year bond sale on Thursday.

Traders said 30-year Treasury yields US30YT=RR pierced a technical retracement level near 4.64 percent, 38.2 percent of the rise in yields that occurred from June 3 to June 11. They said the next target for the 30-year yield would be near 4.58 percent.

At midday, 30-year bonds US30YT=RR were up 1-2/32, their yields falling to 4.62 percent from 4.69 percent on Thursday.

The bond rally occurred even though U.S. consumer confidence rose to a nine-month high in June at 69.0, from 68.7 in May, according to a Reuters/University of Michigan consumer survey index.
