In 2015 our team discovered this highly unique AGN in which we are witnessing the ongoing transition process. Monitoring Mrk 1018 immediate behavior with a joint Chandra/HST observation twice in 2019 is urgently needed and will leverage our extensive multi-wavelength monitoring program built up in the last 4 years. With the proposed data we will study how the X-ray emitting corona and the UV emitting accretion disk respond to the ongoing changes in the accretion rate. The joint X-ray/UV data are also needed to track the evolution of the wavelength-dependent SED (in combination with other wavelength ranges), as well as to understand why Mrk 1018 repeatedly changes its luminosity output. ------------------------------------------------------------------------------------ Observations Description ------------------------ These COS-FUV observations are part of a coordinated multi-wavelength monitoring program combining X-rays (Chandra) and optical observations of the changing-look AGN Mrk1018. Each epoch we obtain a 3 orbit long FUV spectrum with the G140L grating to cover the FUV continuum at high S/N as well as the flux and shape of broad emission lines such as Lya and CIV. ------------------------------------------------------------------------------------ 15612( 3) -
