Multiwavelength analysis of Be/X-ray binaries are crucial to understand the mechanism producing their outbursts. H 1145-619 is one of these systems. From 1997 to 2015, this source was believed to be in quiescence, but from the analysis of INTEGRAL/IBIS and JEM-X data, new X-ray outbursts in 2003, 2004, and 2005 have been identified. To understand the complex behaviour of the source, optical photometric and spectroscopic observations and measurements from the literature have been compared with the X-ray activity of the source, and a global picture of the optical and X-ray variations during the last 40 years is presented.
