NEW YORK - The Statue of Liberty's lights are back on after briefly going dark Tuesday night.

Only the statue's crown and torch could be seen during what the National Park Service called an "unplanned outage."

Speculation grew on social media that this may have been a show of support for Wednesday's "Day Without A Woman" protest.

But the Park Service denied that, and said it was most likely related to the installation of a new backup generator as part of Hurricane Sandy repairs.

The statue's lights came back on just before midnight.

The Park Service says it expects to determine the official cause of the outage Wednesday, and that the statue would be open to visitors as scheduled.
