The comet 2014Q2 Lovejoy in Feb 2015 has moved north to the eastern region of Andromeda in higher evening skies. The coma brightness has been down to about 5th magnitude and about half the visual diameter compared with that in last month, I could observe that the comet has kept its activity yet stretching a splendid bluish ion tail with a length of over 10 degrees.
  The 1st image has been cropped with an equivalent f=1350mm. (View angle: 0.94×0.63°)
  The 2nd image has been cropped with an equivalent f=300mm. (View angle: 4.25×2.84°)
