We are currently making some infrastructure changes and batch retrievals of HST data will likely be slower than usual. Please be patient and don’t resubmit a request for the same data, as this only increases wait times. We appreciate your patience as we work through these updates. The HSTonline data is available for download.

HST History Search

Dataset or Association name
Observations start from hours before to hours after

This form allows you to quickly see what observations surround a given dataset. The search is done for dataset with the same instrument configuration as the given instrument. The original dataset is included in the output, and the rows are sorted by start time in descending order.

To use it, enter the name of an HST dataset (case is not important), select how many hours back you want the start times to occur, and optionally, how many hours forward, and click the Search button to see the results, or the Form button to go to the MAST HST search form, where you can apply more search qualifications.
