Flares don’t cause auroras. However, they are sometimes (often?) accompanied by coronal mass ejections which, if they head our way, can cause auroras. So it all depends on whether or not there were CMEs with these flares and whether or not those CMEs are on a path that will strike Earth. This forecast differs from the one in the posted article.
As it happens, there are a few CMEs headed our way right now according to spaceweather.com .
STRONG GEOMAGNETIC STORM PREDICTED: The sun hurled another CME toward Earth today, and this one looks like it will be a direct hit. The M7.5-class explosion from sunspot 4274 has an unambiguous Earth-directed component. In total, three CMEs will graze or hit Earth in the days ahead: #1, #2, #3. As a result, strong G3-class geomagnetic storms are possible on Nov. 6-8. CME impact alerts: SMS Text.
