Unexpectedly, it is not too faint still now. Diffuse but not so tiny.) 2006 3 23.84 S 10.5 TK 20.3T 100 2 4 GON Ferrerinos - Ribera de Arriba, Asturias (Suburban location.

The comet was blocked by the clouds before twilight ended. So my observation is in the evening twilight. Because observing through thin clouds, it was not easy to see, and my estimation is inaccurate. But it was clear that a diffuse wide object existed.) 2006 2 22.82 S 10.3 TK 20.3T 77 2.0 5 GON Dosango - Santo Adriano, Asturias (Bright zodiacal light.

Very different from my last observation 3 months ago. I was surprised it was faint and not easy to see, although it may be due to the moonlight and low altitude. But the comet was clearly visible anyway with 40-cmL.) 2006 1 1.78 S 10.2 TK 10.0B 25 3 5 GON Camposagrado, León (Altitude: 19 deg.) 2005 12 30.80 S 10.5 TK 20.3T 77 2.5 5 GON Sierra del Aramo, Asturias (Zodiacal light.

The central condensation is not so sharp as before. Now it looks like an ordinary small comet. But moderately condensed still and easy to see.
