In Coma Berenices, at ~ ¾ ° SE of 6 Com. Very weak galaxy, at the limit of my binos. It is located in the same field than M100 and like stars reference mark, I used a quadrilateral forms by SAO 100023, 6 Com, SAO 100021 and SAO 100039. M99 was located just at the south of this figure. After a few minutes of attentive observation, the object finally appeared to me with averted vision. The galaxy seems round and of low size. No other visible details. It was located very close to the zenith.
