The r-band science image for SN 2025brs at MJD = 60647 (left), as well as the corresponding r-band template (middle left) and difference images (middle right), taken from Rubin DP1. The rightmost panel shows the SNR calculated by performing forced photometry on the difference image at every location. The red cross shows the reported location of SN 2025brs. It is clear that the image-subtraction pipelines did not work as expected, presumably due to the bright galaxy that SN 2025brs is embedded in.
