Observation Notes:<\/b><\/p>\n

M99 was difficult to examine, but definitely rewarding. It appeared circular and moderately condensed at first glance. I switched from 120X to 240X and back to try to pick out structure. A star on the edge of the galactic disc helped analyze the position of mottling that began to emerge.<\/p>\n

A brighter patch consistently exited the core on the northeast side and pointed just north of that star. Sweeping the scope back and forth caused a faint, extended patch to appear on the west side, breaking out of the otherwise circular glow. It contained a brighter patch where it joined the main disc. Finally, a sharply curved, very faint arc emerged on the northwest side, inside the halo. I have GOT to spend time with this amazing galaxy at Anderson Mesa or Sunset Crater.<\/p>\n
