Welcome to the Chandra X-ray Center Helpdesk

In order to streamline support requests and better serve you, we utilize a support ticket system. Every support request is assigned a unique ticket number which you can use to track the progress and responses online. A valid email address is required to submit a ticket.

You may also submit a ticket by sending an email to cxchelp@cfa.harvard.edu.

• What operating system & version?
• The full syntax for the command(s) you are running.
