Thanks to Denise for pointing me in the direction of Kevin Pringle's tweet, revealing that YouGov - the most No-friendly pollster of the lot - is about to publish their best poll for Yes of the campaign so far. There are two ways of interpreting that - it could mean the best poll with Don't Knows included (which would imply a Yes vote of 38% or above, and a No vote of anything), or it could mean the best with Don't Knows excluded (which would imply a Yes vote of at least 43%, and a gap of no worse than 43/57). Obviously the latter would be better, but either way it's going to transform our perception of the polling landscape after three successive underwhelming YouGov polls. Taken in conjunction with the pro-Yes swings in the ICM and Panelbase polls, it will bolster the perception that there is now real momentum behind Yes.

I'm travelling on the continent at the moment, but I'll update with the figures when I get a chance.
