The Nature blog has the text of an official OPERA statement:
"The OPERA Collaboration, by continuing its campaign of verifications on the
neutrino velocity measurement, has identified two issues that could
significantly affect the reported result. The first one is linked to the
oscillator used to produce the events time-stamps in between the GPS
synchronizations. The second point is related to the connection of the
optical fiber bringing the external GPS signal to the OPERA master clock.
These two issues can modify the neutrino time of flight in opposite
directions. While continuing our investigations, in order to unambiguously
quantify the effect on the observed result, the Collaboration is looking
forward to performing a new measurement of the neutrino velocity as soon as
a new bunched beam will be available in 2012. An extensive report on the
above mentioned verifications and results will be shortly made available to
the scientific committees and agencies." | e*******n
