Now we can do some interesting calculations. I measured the angular diameter of the comets head to be approximately : 22" or 0.00011 radians.
With the distance from the earth : 6.42 au = 960 400 000 km
Then we can find the diameter of the head : 960 400 000 km x 0.00011 = 105 644 km approximately 100 000 km
The speed of expansion since 1. November (6 days) : Radius/6 days = (100 000/2 km) / 6 days = 8 333 km/day
= 0.096 km/sec. which is close to Halley's comet (0.11 km/sec. calculated at 6.24au from the sun, see link to article)

Compared with Halley's comet, we have observed and calculated dust outflow velocities :
At 1.5 au from the sun : 0.231 km/sec.
at 6.24 au from the sun : 0.231/sqrt(6.24/1.5) km/sec.= 0.11 km/sec. (calculated)
and at 14 au from the sun : 0.045 km/sec. (ref, Sekanina et al. 1992)

This indicates that this outburst of 29P is approximately the same or little smaller than Halley's continuous dust outflow at the same distance from the sun.
