In February and March the comet is moving Southwards through the constellations Cassiopeia, Camelopardalis and Perseus.

The shape of the inner condensation is staying very constant over the months of observation.

Also in February the comet was staying very weak.

One day later the shape of the coma was significantly smaller, but a thin tail became visible: coma 0'20", tail 0'39" in PA 128

The comet is still staying very weak. It lies 3 mag under the expected magnitude.
At this day the comet shows an extended coma without any tail.

After getting back my camera from repair in USA this is my first image with the ST10XME since 6 weeks.
The comet is still very weak (14.7 mag) and is not full-filling its expectations.

The comet's brightness  is not complying with the expected magnitude. Till now I couldn't visually observe the comet. It is very weak(CCD mag 15.7).
Soon it will leave the North Pole region in constellation Cepheus and will move Southwards to the constellation Cassiopeia at January, 14.
The comet has a short tail of 13" in PA138
