The Black Hole X-ray candidate IGR J17091-3624, first detected in 2003 (ATel #149) and well known for its recurrent outbursts and exotic variability patterns reminiscent of GRS 1915+105 (Altamirano et al. 2011, ApJL, 742, L17; Court et al. 2017, MNRAS, 468, 4748; Wang et al., ApJ 963, 14, +2024), was detected to undergo a new outburst in early February (ATels #17034, #17038, #17065).
