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.
