And why would that be?  If it's V-filtered, he reported to AAVSO correctly;
if it's unfiltered, it should have been reported as "CCD":

Multi-letter Codes (Begin in column 38): 

CCD  Charge-coupled device (unfiltered)
CCDB  Charge-coupled device (blue filter)
CCDI  Charge-coupled device (infrared filter) 
CCDO  Charge-coupled device (orange filter)
CCDR  Charge-coupled device (red filter)
CCDV  Charge-coupled device (visual filter)

The observer will have to clarify.
