Source is 2MASS J17255005-2510420 (SIMBAD classification: Long-Period Variable Candidate, LP?), a red giant with 2MASS K=7.735, J=9.415, H=8.214. Currently at i~12.9 apparent magnitude — approximately 1.1 mag brighter than Gaia DR3 quiescent G=14.08. Long-baseline ALeRCE forced photometry shows repeated outbursts since MJD 58,000 (2018). Galactic latitude 5.73 degrees. No prior TNS report within 30 arcseconds. Spectroscopic classification requested to determine nature of outburst. 2026TNSTR2493....1M N
