Aurura alerts seem only to be based on whether there is an ongoing

does someone not issue an alert two days beforehand when there is
such a flare?

Geomagnetic activity is the only really reliable indicator. Fairly
often there will be a flare but no aurora even with earth directed
flare. I look at http://www.spaceweather.com at least once a day, that
announces flares and the chances of aurora activity. Gives me a 24 to
48hrs notice.

They do an alert service but I thought that was a geomagnetic based
one. I assume you are already aware of the York Magnetometer alert
service and ADEC from http://www.aurorachasers.com
