On November 11 2005, HIRES Engineering time at the W. M. Keck Observatory was allocated in order to observe gamma ray burst GRB05111 using the High Resolution Echelle Spectrograph (HIRES) on Keck 1.

These data are an early public release of data from the Keck Observatory Archive (KOA), which began providing public access to non-proprietary HIRES data in July 2006.

The data are also available from the W. M. Keck Observatory's Keck Observatory Archive site.

For help downloading GRB051111 or Deep Impact observations, please see the download user's guide, or contact the KOA Helpdesk.
