Scientific paper

The nearby Sb galaxy, NGC 3227, is an interesting source in many wavebands, and could represent a transitional Seyfert galaxy. Recent X-ray observations show the source to exhibit extreme spectral variability on a timescale of years. Most significantly the X-ray spectrum appears to change from a Seyfert 1-like to a more Seyfert 2-like form. Here we propose a 50ks ACIS-S/HETG observation of NGC 3227 in order to perform an exploratory spectroscopic study. The proposed observations will provide our first insights as to how and why the ionized, circumnuclear material in NGC 3227 might differ from that seen in other objects.
