* Dollar index hovers near seven-week high
* Market eyes developments in Irish debt crisis
* Fed comments marginally hurt greenback

SYDNEY/TOKYO, Nov 17 (Reuters) - The euro hovered near a seven-week low versus the dollar on Wednesday, threatening to deepen a 5 percent slide seen so far this month with no immediate solution for Ireland's debt crisis in sight.
While euro zone finance ministers agreed to lay the groundwork for bailing out Ireland's banking sector with the IMF, Dublin has yet to decide whether to request the aid.
The uncertainty created by the euro zone problems benefitted the dollar, adding fuel to the short-covering rally that on Tuesday drove the greenback to a seven-week high of 79.461 <.DXY> against a basket of major currencies.
Although comments from Fed officials advocating further easing steps if needed briefly pushed down the dollar, traders expect its rally to continue after it rose on Tuesday despite a sharp fall in U.S. bond yields.
"It seems as if the dollar is being bought no matter what factors are in the market," said a trader at a Japanese bank. Many traders suspect more buying back of the dollar is likely ahead of the year-end, when many players close their books.
The euro <EUR=> traded at $1.3500, up 0.1 percent on the day but not far from a seven-week trough of $1.3446 hit on trading platform EBS on Tuesday.
A convincing break there and then at $1.3436, a level representing the 50 percent retracement of the August to November rally, could pave the way for the euro to test $1.3334, the peak of the June-August rise.

The euro drew marginal support after the Wall Street Journal reported that Boston Federal Reserve President Eric Rosengren said the Fed would need to consider more action if the economy weakens, and that Chicago Fed chief Charles Evans said the $600 billion earmarked for purchases of Treasury bonds was a "good place to start."

Their comments came as objections to the Fed's new stimulus effort have grown steadily louder since November elections swept Republicans into control of the House of Representatives, with two U.S. Republican lawmakers now calling on the Fed to focus solely on inflation and ditch its "dual mandate" to promote both price stability and full employment.

]The dollar kept within sight of a six-week high of 83.60 yen yen <JPY=> struck on Tuesday, and last traded at 83.42 yen on Wednesday, up 0.1 percent on the day.
While constant selling from Japanese exporters is keeping the dollar's advance slow, some traders say the greenback could rise to around 85 yen.
On the daily Ichimoku chart, a break above the top of cloud, which sat near 84 yen on Wednesday and will be around 83.70 yen for the next few days, would send a strong bull signal.
Against a basket of major currencies, the dollar <.DXY> <=USD> stood at 79.194, not far from Tuesday's seven-week high of 79.461 after having broken the 78.90/79.10 resistance zone.
It is facing a major support-turned-resistance area between 79.55-80.05, a sustained break of which could point to more strength in the dollar in the medium term.
"It's part of the ongoing trimming of the big trades that started to be put on in real size in late September of weak dollar and risky assets in anticipation of Fed QE spilling into emerging markets," said Sean Callow, a strategist at Westpac Bank.
The Australian dollar <AUD=D4> traded at $0.9760, down 0.1 percent on the day, after having skidded to $0.9725 on Tuesday, a low not seen since Oct. 29.
The Aussie's slide was worsened by persistent worries that China, Australia's largest export market, would tighten monetary policy to keep a lid on inflation and thus risk slower growth.
Still, analysts note such worries proved misplaced earlier in the year and actual activity data from China has surprised on the upside in the last couple of months. (Additional reporting by Masayuki Kitano; Editing by Chris Gallagher)
