Hi Folks,
 
Very interesting orbit for this object on the possible comet confirmation page.
16 observations over an orbital arc of 1.9 days shows a perihelion distance of 0.16AU in October 2018.
If i constrain e=1, I get 0.27AU in mid September 2018.
More observations are encouraged but the current magnitude is quite faint (m=20).
let’s hope the orbit holds true.
 
cheers,
Michael Mattiazzo

Maybe magnitude +4 around August 15. Close to the Sun.

好像目前還15等太暗

未來會如何不知道  看8月吧
