Subsection images (1′ × 1′) of the field of Arp 299. a) NOT V-band follow-up image of SN 2019lqo, b) NOT follow-up image of SN 2020fkb, and c) Subtraction between the images. The tick marks indicate the locations of SNe 2019lqo and 2020fkb. The image scale and orientation are indicated in the left panel. The locations of IR bright main components (A, B, C, C′) of Arp 299 (Gehrz et al. 1983) illustrate that some of these regions are obscured in optical wavelengths.
