The table show calculated outburst expansion speeds. ( How to calculate, see January 14 2025 link under):

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.

Halley's comet 0.11 km/sec.
Comet Hale-Bopp 0.16 km/sec.

The drive gas for the comets' dusty coma seem to be much weaker than for Hale-Bopp. (Both have diameter of ca. 60km ) And the main drive gases for comets' dusty comae are :
Carbon monoxide, carbon dioxide, nitrogen, oxygen, cyanic acid, methane(?) . ref. :
