Object name: NGC5584
NGC 5584 is a rather low surface brightness galaxy in western Virgo 80 to 90 million light-years distant that is just about on the celestial equator. It is another spiral that at first appears rather normal then on second look is rather strange. The northern third is mostly a flocculent spiral in that the arm structure is just a bunch of bright knots in no real pattern. The lower two-thirds has spiral arms but they are strange. The northern arm coming from the core is indistinct and rapidly widens into just a bright region that has little structure. The southern arm is normal looking but then curves north becoming the disorganized jumble that is the northern part of the galaxy. A second southern arm stars from between the two arms and other arms begin and end apparently at random locations. One object I took to be a star knot near the southernmost end of the galaxy is listed in NED as a separate galaxy but with a redshift very similar to NGC 5584. I can't see it as anything but a star knot in the galaxy but it is shown on the annotated image. It was discovered by William Temple but the date is lost to history. It was also seen by Edward Barnard on July 27, 1881.
