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 Mar. 3 (when r=0.84 AU) using the 
robotic TRAPPIST 0.6-m telescope at ESO La Silla Observatory, resulting 
in the following averaged production rates (Haser model with Vp=Vd=1km/s) :  
log Q(OH) = 29.36; log Q(NH) = 27.05; log Q(CN) = 26.96; log Q(C_2) = 
27.20; log Q(C_3) = 26.50; and Af(rho) (526.0 nm) = 6380 cm at 10.000km. 
The activity of the comet has been rising steeply, Q(CN) has been x3
since mid February and x5 since last report mid January. 
Several jets are found to rotate in phase with the gas light curves.

Two sets of narrowband photometry were also obtained on comet C/2011 L4 (PANSTARRS) 
on Feb. 8 (when r=0.86 AU) during the twilight and at high airmass, 
resulting in the following averaged production rates: 
log Q(OH) = 28.60; log Q(NH) = 26.64; log Q(CN) = 26.22; log Q(C_2) = 26.45; log Q(C_3) = 26.02 ; 
Af(rho) (526.0 nm) = 12300 cm.  
L4 PANSTARSS is a very dusty comet with respect to Q(OH) but its composition 
is typical in C2 and CN.
