Variabilidad infrarroja del núcleo activo en NGC 2992

There are galaxies in the Universe that harbour an active nucleus and present variability in the type of emission, varying in their Seyfert type classification, and in their nuclear magnitude. In this work, a photometric study of the galaxy NGC 2992 is presented. In the latest decades, this galaxy has gone through episodes of variability in the optical, infrared, and X-ray ranges. In this contribution, nuclear magnitudes in J band are reported from observations carried on in January 2022 and the magnitude obtained in a 3" aperture is compared with previous reports, finding a variation of 0.8±0.3 magnitudes with respect to 1998.
