This image shows you the comet 2012X1 LINEAR about three months later of my previous obsevation. The comet has positioned in lower southeast dawn skies, around northeast region of Capricornus. An 8th magnitude coma and a thin dust tail stretched in west can be observed.
The comet has passed the perihelion, withdrawing from the sun but closing to the Earth gradually, so the comet has almost same apparent size during last several months. I can observe a visual diameter of the comet with about 5 arc minutes.
  The image has cropped with an equivalent f=2000mm. (View angle: 0.63×0.42°)
