The NOvA Near Detector in its surface building (NDOS) has observed its first event: a cosmic ray muon. From the NOvA spokespersons:
It has taken a tremendous amount of work both at and away from Fermilab to get us to this point. After years of planning and preparations this experiment is about to become very real. This is a very hectic time -- there is still much work to do -- but we hope everyone can take a moment to reflect on what has been accomplished so far. Congratulations to all!!
