- Аннотация: We report another brightening of NGC 2617, an AGN which underwent a dramatic change from a largely obscured Seyfert 1.8 to an unobscured Seyfert 1 between 2003 to 2013 (Shappee et al. 2013, ATel #5010; Shappee et al. 2014, ApJ, 788, 48). Spectroscopy and BVRIJHK photometry from January 2016 revealed that NGC 2617 was continuing to be in a high state (Oknyansky et al. 2016, ATel#9015). We report here a new brightening.
