  Comet C/2014 Q2 (Lovejoy) on March 16, 2015 imaged at its maximum approach to Ruchbah star (delta cassiopeiae),
 the angular distance between them was 9 arcminutes. The strong blue brightness of the star leaves barely
visible the comet tail that extends from greenish coma toward northeast outside of image field.
