V-band light curve and the different image stamps of an archival transient discovered using TUVOpipe at RA = 16:25:29.82, Dec = −29:51:35.6. This source was identified as the long-period variable candidate ASASSN-V J162529.87-295134.3, and it was recovered serendipitously (i.e. it was not the target of the Swift observations) with TUVOpipe running in archival mode in the field of the blazar PKS 1622-297. The red points indicate data points obtained on images that may not have been successfully aligned in the pipeline (see Sect. 3.3.1). We note that the diffuse structure seen in the difference image stamp is likely the result of artefacts in the science image caused by very bright stars in the FoV.
