2059-2113 *MK antenna stowed to let site tech check on the       VAC    100   14
           B rack temperature sensor. There was a temperature                   
           spike earlier and while temperatures have dropped                    
           they are not back to normal.                                         
     2107  MK site tech Tony Sylvester reports that the B rack                  
           problem is a false readback due to moisture. There                   
           is a small leak in the Vertex room roof that is                      
           allowing water to run down into the rack. He                         
           reports that the Vertex room itself is nice and                      
           cool.
