The comet 2014Q2 Lovejoy in that day has positioned at north edge of Aries. Although the coma looks smaller than that in last week, the brightness is keeping 4th magnitude, I could detect it easily with naked eyes. The 2nd image can show us that the comet has a well-proportioned straight-shaped ion tail with a length of about 5 degrees. And in that day the comet, the Pleiades and the California Nebula are forming a triangle.
  The 1st image has been cropped with an equivalent f=1800mm. (View angle: 0.70×0.47°)
  The 2nd image: View angle: 4.12×1.38°
  The 2nd image: View angle: 35.3×24.0°
