Thanks to all for the tips and good info. I pulled out the tandem CB & cleaned all contacts and the flickering stopped. Checked Home Depot and their equivalent is $54 by Connecticut Electric. Mine is Siemens originally installed in 1961.
Here are some odd photos for curiosity. The panel can use some cleaning
-- something for another day.

- wall receptacles are fine.
It is not happening all the time or at a particular time of day. My first guess was a loose connection at the circuit breaker panel, but all the connections there are good, and the breaker is fully on.
I know this is not much info, but all I have at this point. I don't think we have rats, but I can picture a big fat rat chewing on a cable in the attic.
For the electrical folks, how would you go about troubleshooting this?
Thanks in advance.
