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.
