Sunny Aurora ?

I guess that an Aurora may be visible at dawn or dusk, but I had an alert:

11th August 2024 3:00pm
Aurora is likely to be visible from Scotland, northern England and Northern Ireland

.

Right now it is very sunny: my light meter app says 300-400 thousand Lux
- that is a thousand times as bright as it is indoors.

Actually, if I read the aurora alert site's FAQ they do explain why they issue alerts in the daytime.
