| Comment | After several nights of cirrus clouds, it was finally clear here last night, and I was able to view this comet again, this time under good conditions. May 22.19, m1=13.3, 1.0' coma (41 cm reflector, 70x). The coma struck me as "soft" (I can't seem to find a better word to describe it), although there was some distinct central brightening; I'd say DC ~3, perhaps 3-4. I'd almost describe the appearance as "ghostly" -- and remarkably faint for a comet within 0.1 AU of Earth. We are now supposed to have monsoon-type conditions for the next few days, including significant chance of thunderstorms during the possible meteor shower tomorrow night . . . |
