Here are my observed and calculated ejection speeds of the dusty coma so far:

Feb 22, 2026 0.10 km/sec.
Feb 19, 2026 0.09 km/sec.
Feb 15, 2026 0.10 km/sec.

Feb 15, 2025 0.11 km/sec.
Feb 10, 2025 0.09 km/sec.
Feb 06, 2025 0.09 km/sec.
Jan 14, 2025 0.08 km/sec.
Jan 12, 2025 0.07 km/sec.
Nov 14, 2024 0.12 km/sec.
Nov 7, 2024 0.10 km/sec.

Mean : 0.095 km/sec. Standard deviation : 0.014 km/sec.

At approx. 6au :
Halley's comet 0.11 km/sec. ( Relevant because it is well observed and studied. )
Comet Hale-Bopp 0.16 km/sec. ( Relevant because it has approximately the same core diameter, 60km )

Method of calculation is described in the link below from February 14, 2025.
It also show its characteristic snail or Microsoft Edge logo form after an outburst.
