I observed the comet on Mar.11 evening, between 21:25-22:35 (GMT+2).
Comet was in 4oS of kappa Geminorum.
Observing conditions: 0*C, clear sky, NELM ~4.2. The full Moon (low in E) was a great nuissance.

- in 22x32 binoculars: not visible

- in 76/700mm reflector: at magnification 35x, at the first glimpse I didn't see it. But 20-30 minutes after, as my eye got dark adapted (I was hiding from the Moon inside a shelter) I could barely see the comet with direct vision and a bit better but still faint with averted vision. It wasn't enough good visible to make precise estimates. ML=10.7m. Diffuse coma, with slight brigtening towards center.

C/2007N3 (Lulin):
2009 Mar.11.85 UT: m1=6.8:, dia.=&7', DC=2?, no tails, 7.6cm reflector (35x)
[altitude 52*; strong moonlight interference]
(estimates are unsure)
