My Bino observation for tonight was with my Nikon 10x50's. Appeared "dimmer"
tonight based on only my impression from last night. Last night it was a few
arc min south of Bootes Phi and tonight it is a few arc min south of Corona
Borealis Phi (about 25 arc Min in 24 hrs?) Still see it as a pale green but
couldn't make out any tail tonight. Hopefully we'll get a good bright
outburst for Saturday night's public star party...

Easy in my 7x21 Nikons. Sure beats M13 at mag 5.9. Would the calc be 2.5
times
1.4? That's only 3.5x brighter, seems more.
