NGC 411 - Source Properties Well-studied nearby Seyfert 1. Brightest radio-quiet Seyfert < kev Non-variable soft emission from extended, photo-/collisionally ionized environment (e.g., Ogle et al., 00; Yang et al., 01; Schurch et al., 04; Wang et al., 11a,b,c) Strongly variable hard X-ray spectrum (e.g., Caballero-Garcia et al., 12) Strongly variable neutral absorbers (days to years) (e.g., Holt et al., 1980; Yaqoob et al., 1989; Yaqoob et al., 1991; Schurch et al., 02; Puccetti et al., 07; de Rosa et al., 07; Wang et al., ) Seyfert 1 properties: variability, broad Fe K α line (e.g., Yaqoob et al., 199; Zdziarski et al., 02; Keck et al., 1) Tobias Beuchert X-ray Universe 17
