Could we intercept interstellar comet C/2019 Q4 Borisov?

Shortly before dawn on September 13th, Julia de León, Miquel Serra-Ricart, Javier Licandro, all members of IAC's solar system Group, and Carlos Raúl de la Fuente Marcos, from the Complutense University of Madrid, obtained high resolution images and visible spectra of comet C/2019 Q4 (Borisov) using the OSIRIS instrument at the 10.4m GTC, installed in the Roque de los Muchachos Observatory (Garafía, La Palma). Observations were not easy, as the object could only be seen at low elevation over the horizon and small angular separation from the sun. However, thanks to the excellent atmospheric conditions of the Canarian Observatories and GTC's expert telescope support astronomers, these challenging observations were successfully completed.
