Optical monitoring revealed that the dramatic dimming phase stopped, suggesting that the accretion disk is in a major reconfiguration phase. The combined deep exposure will reveal which spectral components have changed since a high S/N XMM spectrum was taken during the bright phase a few years ago. Comparing the two AO17 observations will allow us to look for spectral changes on half-year timescales. These two XMM observations will fill the gaps of our already accepted low S/N Chandra monitoring program on Mrk 1018. The joint HST observations will allow us to establish the states of the accretion disk and how this connects to the X-ray corona. ------------------------------------------------------------------------------------ Observations Description ------------------------ These COS-FUV observations are part of a coordinated multi-wavelength monitoring program combining X-rays (XMM-Newton) and optical observations of the changing-look AGN Mrk1018. Each epoch we obtain a 2 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. ------------------------------------------------------------------------------------ 15440( 4) - 14-Dec-2018 14:26:37 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 MRK-1018 GALAXY, ACCRETION DISK, RA=02H06M15.9888S +/- 0.25", J2000 V = 15.0 +/- 0.5 300 counts/s in the 4s BLR, NUCLEUS, SEYFERT DEC=-00D17'29.18" +/- 0.25" long COS NUV (PSA and MIRRORA) acquisition images from Feb 2017 Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
