NEW YORK, April 21 (Reuters) - Brent oil futures <LCOc1> seesawed near unchanged after slipping off a 32-month high Thursday as traders took some money out of recently rising energy markets before a holiday weekend.
U.S. oil futures <CLc1> rose in choppy trading as a weaker U.S. dollar, which fell to its lowest since 2008 against a basket of foreign currencies, stoked risk appetite for the cheaper U.S. benchmark crude.
Separate reports showed the pace of factory activity in the U.S. Mid-Atlantic region fell in April and U.S. initial jobless claims held above 400,000 which cast some doubt on the pace of U.S. economic recovery and how it could affect energy demand.
The dollar tumbled for a third straight day and the dollar index <.DXY> neared an all-time low.
Brent crude for June <LCOc1> edged up 10 cents to $123.95 a barrel by 2:15 p.m. (1815 GMT), having earlier pushed up nearly $1 to $124.81, the highest since April 11.
U.S. crude <CLc1> for June rose 70 cents to $112.15, just off an earlier intraday high of $112.48.
Brent's premium to its U.S. counterpart <CL-LCO1=R> narrowed by 60 cents to $11.80 a barrel.
"Brent has lost a little momentum in its rally," said Gene McGillian of Tradition Energy in Connecticut. "But it's still got a big advantage to U.S. crude and that spread is unwinding a bit now."

].Unrest and geopolitical threats to oil supplies in Africa and the Middle East remained supportive for prices, and brokers and analysts said the risks would limit incentive to take profits after oil prices gained this week.
Brent was trading within a few dollars of the 32-month high of $127 a barrel reached earlier this month, a level which forecasters in consumer countries have said is already high enough to hurt world oil demand.
The dollar has weakened this week after Standard & Poor's cut its outlook for U.S. government debt to negative, leading some foreign exchange analysts to tout the euro's potential as an alternative reserve currency. [
