NIR IRAC images showing the detection of the progenitor. Left: pre-SN images showing the progenitor (red) circle in channels 1 (top) and 2 (bottom). Middle: post-explosion images in channels 1 and 2. Right: difference images (post-explosion − pre-explosion image). There is a source visible at the progenitor position in both channels. We detect it with an S/N of ∼10 (≫3σ) in channel 1, and an S/N of ∼4 (∼3σ) in channel 2.
