On behalf of the CanariCam Science Team, we report the first detection at 10 micrometers of the Type Ia supernova 2014J in M82. Four 200s (on-source, excluding overhead) exposures, two centered at 10.3 micrometers and two centered at 11.75 micrometers, were acquired with CanariCam at the 10.4-m Gran Telescopio CANARIAS (GTC) starting at UT 2014 Feb 10.12. We used the coordinates given in ATel #5821. The supernova is visible at both wavelengths, and is the only source detected in the imager field of view. The source location in the field of view was 3 arcsec from the imager center (i.e., the nominal location of the supernova), which we believe is within the absolute pointing accuracy of the telescope that night. The flux densities of the supernova are (7.2+/-2.9) mJy at 10.3 micrometers and (12.4+/-3.0) mJy at 11.75 micrometers. The combined value is (9.8+/-2.1) mJy at a nominal wavelength of 11.0 micrometers. These data were obtained using the CanariCam Guaranteed Time. The GTC is a joint initiative of Spain, the University of Florida, and Mexico.
