(meteorobs) Expected Lunar "ZHRs" for the Moon during 2001 Leonids

> Asher/McNaught:

> Maximum ZHR: 5247.3
> Time of maximum: Nov 18 at 16.3200 UT
> Maximum flux (down to 1e-5 g): 0.26E+01 km^-2 hr^-1
> Fluence (down to 1e-5 g): 0.25E+01 km^-2

> 1799 Max. ZHR: 442.0 on Nov 18.6000 Distance: 0.00059 AUs
