Hubble Observation Problem Reports (HOPRs) provide a mechanism for you to inform STScI when a problem has occurred with the implementation, scheduling, execution, or data processing of your observations. It is also the means by which the Principal Investigator (PI) makes the request for failed observations to be repeated.

To allow us to address the problems noted in HOPRs in a timely manner, the HOPR submission deadline for requesting repeat observations is 3 months from the time of data distribution.

If one or more of your HST observations apprear to have a problem, go to the HOPR Submit Page, and complete the form to the fullest extent possible then press the "submit" button. The form will be electronically mailed to the the HOPR analyst, to the Contact Scientist, to the Program Coordinator, to the submitter (if this option is selected), and to the Principal Investigator (PI) for verification.

STScI will investigate the problem before a decision is made. The PI will get a response within a month, including an explanation. Note that failed observations will not be considered for rescheduling unless an explicit request is made by the PI. It should be noted that a repeat of observations automatically causes old data to be released to the public archive.

If you have additional information that you would like to include with your HOPR, please e-mail your Program Coordinator or help@stsci.edu.
