Centered at HIP60490 (Mag. 6.68). Beautiful binocular cluster with several brilliant stars, competitive with Pleiades and Hyades. One magnitude 9.0 star picked up (TYC1991-1401-1) as well as several 8 and above. With naked eye, 8 of the 9 stars of Boötes (in the main asterism, not counting pipe) were visible, as were four stars of Corona Borealis. A tree branch obscured part of my view. I picked up far more stars than my earlier observation on April 9—partly from observation experience, partly it was closer to zenith, and partly, there was no glow from the moon.

Oh be a fine girl--kiss me!
