Uploaded 4/28/02

A bright face on spiral shining at magnitude 10.4, with plenty of core details. This Sc spiral spans 5.4 arcmins in size, and is one of the brightest spirals in the sky. This galaxy contains classic plume structures, lanes of nebulosity perpendicular to the arms seen well on the right side of the core. The Wray Atlas mentions that large amounts of star formation is going in in both the arms and plumes in this object.
