This archive allows you to retrieve WHT/INT/JKT observing logs since 1993. For older searches please refer to the ING Archive. It is possible that some logs are missing, most likely because they were never created (some reasons can bad weather preventing accessing the telescopes or no ING detector used). Observing logs less than one year old (the proprietary period) are not available via this interface. Please contact your support astronomer or ING Head of Astronomy to obtain a copy of a log created during the last year.
