Analysis of the auroral observations made by the crew of the U.S.S. Jeanette between 1879 and 1881 Figure S1. The journey of the USS Jeannette from San Francisco to the Arctic 1879 – 1881. (http://www.naval-history.net/OW-US/Jeannette/USS_Jeannette-1879-1880.htm) The position of the magnetic North Pole between 1879 and 1881 is shown in red.Figure s2. Monthly Aurora frequency over the 2-year period the USS Jeannette spent drifting with the iceFigure s3. Fraction of aa observations for which the Jeannette recorded auroral sightingsFigure s4. Variation in the frequency of auroral observations with lunar ageFigure s5. Frequency of observation time. As might be expected most observations were reported between the hours of 21:00 and 04:00. All observations between 07:00 and 17:59 (inclusive) were reported during periods of polar night.Figure s6. The Jeannette year (averaged over 2 years and on ship time). This shows the monthly variation in aurora observations and cloudy days. During Polar night the Sun remains below the horizon resulting in several weeks of constant darkness. During midnight Sun the Sun never sets producing several weeks of constant daylight.
