Hi Orestis
I haven't seen you around for some time, great to hear from you!
You're observations were spot on. On the 15th it reached mag. 4.9
And last night (16th) had it at 4.5 (some say 4.4)!
We were all excited on facebook as we were seeing it naked eye!
The latest light curve (17th) shows it has dropped down to 5. Bye bye star,
was a brief visual appearance.
So glad I nabbed it when I did.
Should still be a naked eye star from a dark site tho. But I couldn't believe I was seeing it despite the moon in the way and thru light pollution.
Regarding the colour- I asked around on facebook and people (like me) were seeing it as yellow. I guess it depends on our eye's perception.
Tom, that's a fantastic comparison image!
