Bob Nelson's O-C files for EBs 2012 edition

The AAVSO is happy to provide a copy of Bob Nelson's O-C files for Eclipsing Binaries for 2012.  These files can be used for observation planning, and are a valuable resource for EB observers.

Thanks once again for Bob Nelson for providing this service to the EB community.
