Meteor observers will have been recording some Quadrantids as they approach maximum rates. Their peak is of short duration, only a few hours, and is predicted to occur after midnight on January 3-4, although various data sources give slightly different time windows.
Their activity profile from multi-year NEMETODE data is attached. (Solar longitude 283.0 degrees equates to 2023 Jan 3 23:20 UT.)
The Quadrantid radiant will be climbing throughout the night but their maximum activity coincides with a gibbous Moon only two days before Full, diluting a meteor shower that can otherwise present a zenithal hourly rate of 80. Cameras facing north should have darker skies, and narrow-field lenses will fare better than wide-angle systems in these bright skies.

The item about the Quadrantrids on the 10pm BBC News with Reeta Chakrabarti was illustrated with three polar region images “from Northern China last year”. Two of these, including the one she held her hand up to to demonstrate the meteors, had (despite some nice star trails) not a single meteor captured…
At least they tried I suppose…
