Abstract

ArgusSpec, a fully autonomous low-resolution rapid follow-up spectrograph, has been optimized for stellar flare follow-up by prioritizing high speed follow-up, optical efficiency, and wavelength coverage. Stellar flares are challenging transients to follow-up at a large scale due to their spacial and temporal unpredictability and their sub-minute rise in flux followed by an exponential decay. We present performance data from commissioning along with results from operations with a real-time transient alert stream from Argus Pathfinder, located at the Pisgah Astronomical Research Institute in western North Carolina alongside ArgusSpec, and Evryscope North, housed at Mount Laguna Observatory.
