Dear Members of the HLS Community, 

On Monday, July 22nd, HLS will be conducting an upgrade to the Helios system between 7:00 AM and 9:00 AM. During this period, you will neither be able to log in to nor access any functions of the system.

Anyone needing to access the HLS Course Catalog during this time can do so via the Harvard University Course Catalog.

If you have any questions or concerns, please do not hesitate to contact the ITS Service Desk at

Thank you,
