More photos from the 12/13 January night. The image above is a view opposite to the spotlight. Seen is blue circle, diffuse, Wegener and subhelic arcs. Below are two more images, the blue-minus-red image shows the “column 351/361”, which is the Kern arc equivalent of 46° supralateral arc. The lamp is about 5 degrees below the camera.
No I haven’t. Actually, I doubt if anyone has seen Kern in solar displays including Mr. Kern himself. All observations seem dubious. If I had to put my money on one display nevertheless, I would go for Saskatoon. The display was of the magnitude to give birth for visual Kern. Ripley and Saugier just forgot it was colored. About the spotlight displays, I have this recollection that Luomanen & Mikkilä thought of having seen Kern with the eye once, but for the discussion on whether any of the historical observations is a real deal we want to get that visual from solar display. So although the Kern arc has been photographed, it still has some of that mystery left.
have you seen the Kern arc with naked eye like 1895 H.F.A. Kern?
