The comet 2013X1 PanSTARRS in that day has positioned at about 2.5 degrees ENE of beta And in higher evening skies with a coma brightness of 10th magnitude, almost stable with my previous observation in last month. A short dust tail with about 5 arc minutes in length has stretched toward east direction, and you can see that the greenish ionized composition is surrounding around the coma.
  The image has been cropped with an equivalent f=2000mm. (View angle: 0.63×0.42°)
