Notes: Known as the Grasshopper Galaxy. The HST website quotes a distance 500 million light years. I saw it as a faint oval glow visible most of the time with DV. The oval is elongated 5:3 in an EW direction. There were hints of structure at the limit of visibility. The tidal tail which runs S from the E end of the galaxy was not seen. A separate galaxy, PGC 26124 mag. 15.4 is nearby to the S. It is a small round glow readily seen with DV. |
