OSETI astronomers find their own 'WOW' signal

OSETI is a version of the Search for Extra-Terrestrial Intelligence that is trying to find Optical signals being sent with laser pulses, figuring that an advanced intelligence will use lasers rather than old-fashioned radio for its communications. While I've had my doubts about SETI, seeing as how its rationale is not only looking for ephemeral needles in very large haystacks, but also betting that the needle owners are extraordinarily careless about their needles.
Nonetheless, these guys found something weird:

in the first week of last December (2008) Bhathal's team detected an unusual strong laser signal that could not have been identified nor did it re-occur since: "It may be a glitch in our equipment, or some astrophysical phenomena (e.g an optical pulsar) or some unknown source. We are still investigating it",

This is OSETI's equivalent to the famous 'WOW' radio signal of the 1970s.
