Optical variations of OJ 287, ON 231, and OQ 208
Creators
Description
Optical observations of three Ohio radio sources made during the early part of 1972 are presented. Old plate collections have yielded a 20-year period of observations of OJ 287, with a possible indication of "intraday" variations; OQ 208 is now suspected to be a long-term optical variable. Subject headings: radio sources - variable stars
