J. Emilio Enriquez, Andrew Siemion, T. Joseph W. Lazio et al., 2018. _Research Notes of the AAS_.

Green Bank Telescope observations of 13 December 2017 across 1.1-11.6 GHz searched for narrowband signals and found none, placing a limit of 0.08 W on an omnidirectional transmitter on the object. RNAAS 2, 9. The raw data are in the Breakthrough Listen open archive.
