Recent Monitoring of Markarian 817
Abstract
Mrk 817 is a Seyfert 1.2 AGN at a redshift of 0.03145 (Strauss & Huchra 1988, Morales et al. 2019). Prior monitoring with the Neil Gehrels Swift Observatory revealed an unusual lack of connection between the UV and X-Ray emission that is often seen in Seyfert galaxies (Morales et al. 2019).
