ISR 2017-02: Bright Object Protection Considerations for M Dwarf Flare Events
We provide clear and concise guidance for Guest Observers and Contact Scientists to evaluate the health and safety of the instrument while observing M dwarfs, taking into consideration current scientific research about the frequency with which large flare events occur, and a risk tolerance level for causing an inadvertent detector shutdown due to overlight conditions from a large flare during an observation.

Space Telescope Imaging Spectrograph

The Space Telescope Imaging Spectrograph (STIS) was installed onboard HST during Servicing Mission (SM) 2 in 1997 and operated until an electronic failure in 2004. It resumed operations with all ultraviolet and optical channels in 2009 after it was successfully repaired during SM4.

STIS is a versatile imaging spectrograph, providing spatially resolved spectroscopy in the UV and optical, high spatial resolution echelle spectroscopy in the UV, solar-blind imaging in the UV, and direct and coronagraphic imaging in the optical. Further information about STIS instrument characteristics and performance over time is available on the STIS web pages in Handbooks, Reports, and Newsletter articles.
