The SN is undetected by {\\it SOFIA}, but the upper limits obtained, combined with new and archival detections from {\\it Spitzer} at 3.6 \\& 4.5 $\\mu$m allow us to characterize the composition of the dust present. Dust in other Type IIn SNe has been shown in previous works to reside in a circumstellar shell of material ejected by the progenitor system in the few millenia prior to explosion.
