     reflector) "Invisible (date in MBM) is wrong, would be only 6h before

     the previously observed gray area was 1/3 of July 22 and V 
     shaped and fanned out across the floor. Could see hint of knot 
     seen before. Craters named in 7/23/88 (#319) were all normal 
     this time too". Is it possible that this report refers to the

     in the Cameron catalog? The Cameron 1978 catalog ID=333 and
