Unless there is something wrong with my math, I calculate that this thing would be at Mag 13.9! H = -8.2 mag and from this m = 13.9 mag

using:

D = 1329/pv^(1/2) * 10^(-0.2*H)

I used Jupiters Diameter and albedo (80000km and 0.52)

m = H + 2.5 Log10(d1^2*d2^2/(px*d3^4))

d1 = distance Sun to body (=15,000)
d2 = distance Observer to body (=15,000)
d3 = distance observer to Sun (=1)
px = 2/3 = the phase integral (ie same as the full moon)

Cheers
