Unknown digital mode heard

I've been seeing a new digital mode in the JT65/JT9 areas on HF lately.

It appears on the waterfall to be a multi-tone mode and uses the same 1 minute fixed timing of JT65/JT9 but has a bandwidth of about 50 Hz, i.e. narrower than JT65 but wider than JT9.

Anyone have a clue what this might be?
