LONDON, Sept 30 (Reuters) - European shares fell for a fourth straight session on Thursday, with concerns about deeper fiscal cuts in Ireland and Moody's downgrade of Spain's government bond ratings keeping investors cautious.
At 0902 GMT, the FTSEurofirst 300 <.FTEU3> index of top European shares was down 0.4 percent at 1,060.77 points after hitting a three-week closing low on Wednesday. But it was up 3.5 percent this month and was on course to post the biggest quarterly rise in a year.

"Investors are nervous and want to see this problem solved. But the big problem is that it will not be solved in the short term," said Koen De Leus, economist at KBC Securities, referring to Ireland's fiscal condition.
"Some uncertainty has gone, but investors will continue to be very cautious."
Financial stocks featured among the top losers, with the
STOXX Europe 600 banking index <.SX7P> falling 0.6 percent.

Sentiment also worsened after Moody's cut Spain's credit to Aa1 from AAA, removing the last of its highly-valued triple-A ratings, but saying it did not expect to cut again soon thanks to efforts at fiscal reform. [ID:nLDE68T0FF]
Investors waited for a slew of macroeconomic numbers later in the day for some indication about the U.S. Federal Reserve's move in the coming months related to quantitative easing.
The U.S. Labor Department is scheduled to release first-time claims for jobless benefits for the week ended Sept. 25 at 1230 GMT. Economists forecast a total of 460,000 new filings, compared with 465,000 in the prior week.
The Commerce Department will announce its third estimate for second quarter gross domestic product growth also at 1230 GMT. A Reuters survey forecast a 1.6 percent annualized pace of growth, a repeat of the second estimate.
The market will also keep an eye on the Institute of Supply Management Chicago's September index of manufacturing activity, due at 1345 GMT. Economists expect a reading of 55.9 compared with 56.7 in August.
Analysts advised caution in buying equities following mixed macroeconomic numbers in the past weeks.
"If you buy equities, buy with fear. Be prepared to know where the sell button is," said Giuseppe-Guido Amato, strategist at Lang & Schwarz in Frankfurt.
"We have problems and the fundamentals are not healthy."
However, losses were limited by stronger energy shares, which tracked crude oil prices that were set to close September with the strongest gain in seven months after stockpiles at the world's largest consumer declined.
