Abstract (from CDS):

We have used the BeppoSAX satellite to study the broad band (0.5-100keV) X-ray spectrum of the Seyfert 1.5 galaxy MKN6. The source is characterized by a power law of Γ=1.7 +0.08–0.07 and there is no strong evidence for either a reflection bump or a high energy cut-off. We have detected a narrow iron line at 6.4keV (rest frame) with an equivalent width of 98+33–35eV. MKN6 also exhibits strong and complex absorption. At least two components (NH1=1.34+0.4–0.4x1022cm–2 and NH2=4.18+2.2–1.3x1022cm–2) are present and they both partially cover the source with covering fractions of ∼90% and ∼50% respectively. Comparison with a previous ASCA observation indicates that in both absorbing columns the NH is variable over a 2 year timescale, while the covering fractions are constant over the same amount of time. The state of each absorber is cold or mildly photoionized. The Broad Line Region (BLR) is suggested as the possible location for this complex absorption.
