Pan-STARRS i-band pre-flare image centered on the host galaxy position of the transient event AT2019aalc. The object located to the west of the galaxy core is a foreground star. The green contours represent the pre-flare FIRST radio observations taken at 1.4 GHz. The lowest contour level is drawn at 3σ image noise level corresponding to 0.4 mJy beam⁻¹. Additional positive contour levels increase by a factor of two. The peak brightness is 5.8 mJy beam⁻¹. The red circle points to the Swift-XRT 0.3–10 keV astrometrically corrected position of AT2019aalc, determined using the Swift-XRT data products generator (Evans et al. 2014). Its size indicates the 90% confidence positional error.
