I’m wouldn’t really expect an “uptick” on the far north routes since in my experience see aurora of some sort probably 30% or 40% of the time on those routes, even when the alert sites aren’t promulgating anything significant, however anything seen would have probably been a more impressive display than the norm.
There may have been an “uptick” in sightings from more southerly routes ( e.g. those crossing the Martimes heading out towards the Atlantic tracks) since the CME did produce a fairly significant display as seen from ground level across southern Canada and the Northern US,
On that point/to answer Lantern10’s question:
From the spaceweather.com website this morning:
https://www.spaceweather.com/
FWIW I’m on a e-Mail alert/info list with a UK aurora observing group and there were no alerts last night for anything significant seen from the UK,I’ve not seen any updates from the group this AM, so it sounds like a significant display but not the power surge/power blanket level producing display that was being warned of in some outlets.
Reason is these days it is relatively straightforward and easy to see Coronal Mass Ejections (CME) blasting away from the sun, it’s still very difficult to predict how they will react with the Earth’s magnetosphere and upper atmosphere once the products of the CME actually get here
