The dust tail of the comet points ti an unusual direction. I have a simulation software for dust tails and analysed the situation with it.
For comparison I used this image from Michael Jäger. The dust tail is 45' long in points to NW.
Appending you find my simulation result which is quite similar. From the parameters of the simulation we see what happens:
- The tail consists of very large particles in the range between 30 µm and 100 µm. This is unusual large, normally we find 0,5 µm ... 10 µm.
- The particles left the comet with s rather small velocity, around 50 ms/s. Normally we find around some hundred meters per second. But large particles are harder to accelerate
- Dust particles will be destroyed / fragmented by the solar radiation in some days. These large particles live much longer, around a quarter of a year. This is not surprising because larger particles resist longer to radiation.
As you may see in my simulation the dust tail is not symmetric and larger extended to SW. If you look careful at Michael's image you may find a hint of it. The central condensation is positioned slightly above an to the left form the center of the visual coma (which contains parts of the dust tail).
