SUBJECT: NRC1 Clock Jump 

The Auxillary Output Generator at NRC experienced a failure of its battery
backup at approximately 14:00 UTC on Feb 10. The event occurred during a 
routine test of the site's Auxillary Power Unit. 

This caused a reset of the NRC1 TurboRogue and a jump of ~200 nsec in
offset.  There is also a slight change in frequency. 

The battery backup system will be replaced to minimize the likelyhood of
future occurances.
