1 M31 Andromeda<br />
Galaxy<br />
Visibility Description Sketch<br />
00:45 41:00 5x3 bright Shelf below M110; sides extend to<br />
edges <strong>of</strong> M31, confusing Andromeda<br />
Galaxy's size (possible explanation for<br />
reports that vary from 3 to 5 degrees<br />
wide); there's a curved arc to the<br />
southeast that almost completes a<br />
circle <strong>of</strong> IFN around the galaxy; the<br />
deflected arm to the northeast<br />
extends to the IFN making me suspect<br />
that the deflected arm is actually an<br />
extension <strong>of</strong> the IFN; for images see<br />
