Comet C/2017 E4 (Lovejoy) imaged in March 31, 2017 only twenty days after its discovery and during maximum approach to Earth to 0.6 AU. It is inn outburst and increasing its brightness from magnitude 15 when discovered by Terry Lovejoy up to magnitude 7 at the time I took this image. The comet then threw an ionic tail more than one degree long, going out of the field toward west (upwards). It shows a greenish coma of a diameter of 8 arcminutes with flattened shape, a trace of possible disintegration during its next approch to the Sun, such as succeeded only ten days subsequently of taking this image.
