Title

C/2018 DO4: Mag. 15.7 for a diameter of 8 pixel (10".7) and fan-shaped tail (about 45 ° wide) of 3'.0 in pa 17 ° (about half the width of the tail). 30x75sec with filter C. The fan-shaped tail is very interesting and also seems much more active than my last observation of October 6th. With the Larsen-Sekanina filter you notice a faint and long jet going out upwards a little to the right. It was not present on October 6th (observed with filter R).
