Quiet aurora arc - 8.7.2022 at 00.35 - 8.7.2022 at 01.00 Ashville, Manitoba, Kanada Observation number 107546

Visibility II / V

By the time the sky got dark in Manitoba, the geomagnetic storm from CME was over.  Our data showed that possibly wind from coronal hole arrived.  We observed a faint diffuse arc from 12:15 to 1:00 a.m. Central Daylight time.  The possible dunes appeared at 12:35 and moved westward.  We ended observation just before 1:00 a.m.
