Comments

On May 11.4, there was clearly something at the position of the comet, but it may require further confirmation (DSS shows some group of mag. 16-17 (?) stars there...)

May 19.5: Observed in the best conditions (stars to magnitude 15.4), small and difficult, but somehow also confirms May 11.4 observations, with a 15.3 mag star that was next to it (seen on the 11.4 but maybe partially included in the mag estimate).

June 17.41: m2 = 14.2 (+/-0.2) (169x256 L)
June 19.53: m2 = 14.2 (+/-0.2) (169x256 L)
July 03.32: m2 = 13.8 (+/-0.2) (169x256 L)
July 04.33: m2 = 14.2 (+/-0.2) (169x256 L)
