The discovery of 2I Borisov presents the second confirmed interstellar object and the first active interstellar body. 2I Borisov’s apparition provides the unique opportunity to study up close planet formation in a different environment and compare this object to the small body populations originating from our Outer Solar System: Jupiter-Family Comets, Long Period comets, and Kuiper belt objects. With 2I Borisov speeding through the Solar System in a trajectory nearly perpenidcular to the ecliptic, we have a brief window to characterize this interstellar comet’s physical properties. We request near-simultaneous grJ photometry with GMOS-N and NIRI so that we can measure the color of the dust comae/tail. These observations will enable comparison of 2I Borisov to previous observations of Solar System comet coma and place 2I Borisov in context with our identically observed comprehensive sample of KBOs plus instellar object ‘Oumuamua observed in grJ with Gemini North.
