C. Opitom, E. Jehin, J. Manfroid, and M. Gillon, Liège University report 
that they obtained one set of narrowband photometry of the long 
period comet C/2012 F6 (Lemmon) on May 15 (when r=1.21 AU) using the 
robotic TRAPPIST 0.6-m telescope at ESO La Silla Observatory, resulting 
in the following production rates (Haser model with Vp=Vd=1km/s) :  
log Q(OH) = 29.0; log Q(NH) = 27.2; log Q(CN) = 26.6; log Q(C_3) = 
26.1; log Q(C_2) = 26.8; and Af(rho) (526.0 nm) = 3200 cm at 10.000km. 
We follow the comet since May 6 several times a week and its activity is now 
slowing down regularly since perihelion.  

A complete set of narrowband photometry was also collected on comet C/2013 E2 (Iwamoto) 
from April 15 to 17 (when r=1.51 AU), resulting in the following averaged production rates: 
log Q(OH) = 27.7; log Q(NH) = 25.6; log Q(CN) = 25.2; log Q(C_3) = 24.7; log Q(C_2) = 25.2; 
Af(rho) (526.0 nm) = 165 cm.  

On May 16.0 UT we noticed comet 63P was 2.1 magnitude brighter (with R=13.5 , aperture 8") 
than 5 and 10 days before (with R=15.6 and R=15.7 respectively, same aperture). 
The onset of the outburst must have been very close as the inner coma was sharp (4") 
in all the filters. But the day after, on May 17.0 the CN coma was much more extended and we derived 
a log Q(CN) = 25.2 and a Af(rho) (526.0 nm) = 350 cm with a large dependance with the distance 
to the nucleus.
