Visibility IV / V
Northern lights from Turku on the Ruissalo bridge and a nearby field. A little later, the play grew further and even Korona was handsomely visible at these latitudes. Great play and adjusts it but still favors the enthusiast :)
Did I mark the horizontal overlapping stripes in the triple and quadrangle in unrecognized shapes?
EDIT: Figure 1 shows the lens reflection in the upper right caused by bright artificial light (light pollution) on the surface of an 8 millimeter lens.
The "horizontal stripes" of the mystery forms, on the other hand, appear in Figures 3 and 4.
