The IBM 1130 line-printer sheet with the sequence 6EQUJ5 circled in red and "Wow!" written in the margin. Donated by Ehman to the Ohio Historical Society (now Ohio History Connection); the accession record was not reachable in this pass (the society's site is behind a bot check) and should be confirmed. The Commons scans of the printout (public domain, released by the observatory) come in through
