The New York Sun, a Manhattan daily newspaper launched six years ago, might close at the end of September unless it can find new investors willing to save it, the paper's editor-in-chief told readers Wednesday.

Seth Lipsky wrote on the newspaper’s website that “the Sun is now at a crossroads,” citing “circumstances that may require us to cease publication at the end of September.”

However, Lipsky said in an interview that he would discourage the readers to assume from this statement “that the paper is doomed.”

“It’s probably the tightest spot we’ve been in, but we’ve been in a lot of tight spots,” he said.

The Sun, which took its name from a legendary publication that folded in 1950, was launched in 2002, funded by a group of investors led by former newspaper mogul Conrad Black. It currently has about 110 employees and numerous freelancers.

The Sun publishes five days a week and gives away about 75,000 copies per day.

Lipsky said that the original investors were prepared to pump more money into the newspaper, but they still cannot cope with the Sun’s financial deficiencies. He declined to say how much the paper loses, or how much money is needed to save it, but said the figures were “some tens of millions of dollars.” Managing Editor Ira Stoll declined to comment on that.

In his letter, Lipsky said that the newspaper’s team was in discussions with a number of investors and newspaper proprietors, but it is not sure whether the negotiations will be successful.

The Sun is co-owned by Lipsky, Stoll and a group of investors whom Stoll declined to name.
