* Some worry better-than-expected numbers could hit gold demand * Strong dollar after central bank easing pressures gold * Spot gold may fall to $1,586/oz -technicals * Coming Up: U.S. June non-farm payrolls; 1230 GMT (Updates prices) By Rujun Shen SINGAPORE, July 6 (Reuters) - Gold remained on track for a second straight week of gains on Friday, though it was little changed from the day before as investors waited for more U.S. jobs data to help gauge the health of the world's top economy and provide trading cues. Some traders said Thursday's private U.S. employment data indicated that key non-farm payroll numbers on Friday could also be robust, dampening hopes for further easing by the Federal Reserve and hurting appetite for commodities. "People are concerned that tonight's non-farm payrolls figures might be better than expected, which will decrease the chances of quantitative easing by the Fed - bad news for gold," said Yuichi Ikemizu, head of commodity trading, Japan, Standard Bank. A series of central bank rate cuts on Thursday only served to stoke investor fears about global economic growth, with a stronger dollar in reaction to a move by the European Central Bank putting a damper on gold prices. The dollar index gained more than 1 percent - its biggest daily rise in nearly eight months - in the previous session, while the euro struggled near five-week lows against the greenback. Spot gold was little changed at $1,603.75 an ounce by 0628 GMT on Friday, on course for a weekly rise of 0.4 percent. The U.S. gold futures contract for August delivery edged down 0.3 percent to $1,604.10. Technical analysis suggested that spot gold could fall to $1,586 an ounce during the day, said Reuters market analyst Wang Tao. Thursday's data showed that U.S private employers stepped up hiring in June and the number of Americans filing new claims for jobless benefits last week fell by the most in two months, hopeful signs for the struggling labour market. The physical bullion market remained subdued, with buyers sidelined after prices rose above $1,600 and potential sellers eyeing $1,620 or above, dealers said. "The current price level isn't attractive enough to lure buyers back," said Peter Tse, director at ScotiaMocatta in Hong Kong, adding that jewellers were likely to enter the market if prices dropped to $1,550 to $1,560. Most Asian currencies were on the defensive against the dollar, which diminishes the purchasing power of buyers holding these currencies, he added.
