Latitude by observation meridian altitude ✱ Aldebaran 6.30pm N. 74° 59' Longitude by chronometer from observation time sight Venus E. 171° 56' 30" Water expended during the preceding 24 hours: 35 gallons Water distilled during the preceding 24 hours: 35 gallons Coal consumed during the preceding 24 hours: 290 lbs Coal remaining on hand at noon: 31 tons 178 lbs Max. temperature = -0.5° Min. temperature = -18.5° The pumping forward is done by hand at the spar deck bilge pump, and such water as filters aft through and under the bulkhead into the fire room is pumped out by hand at the bilge pump attached to the main engine. The steam cutter's boiler is used for distilling. Sounded at 10am in 57 fathoms. Brown mud. A very rapid drift to E. x N. being indicated by the lead line. Weather bright and pleasant, and after 9am the sky was absolutely cloudless. The day opens with strong southerly winds which moderate rapidly after noon, and veer steadily reaching E.N.E. by midnight and there blowing in light airs. Barometer falls slowly until the wind in veering passes west when it rises rapidly. Steadily falling temperature. Sunrise 9h 5m, sunset 3h 5m. At 3am a very beautiful aurora was visible, and is thus described by Passed Assistant Surgeon Ambler: "An auroral curtain arch extended from N.W. x W. through the zenith to S.E. x E. It was composed of striae of great brilliancy, while between them were masses of luminous nebulae not so intense in brightness. The lower edge of the whole arch was frequently interrupted in its regular form, as if made up of rays of greater intensity and longer axes than the luminous nebulae before referred to. Pulsations of the most brilliant purple, green, and white colors went from one end to the other. As I looked, the arch flashed into a corona. The rays ascended, forming as they lengthened, a hollow cane into the inside of which I could see. The most rapid change of color took place up and down the side of the cane (the colors being more beautiful than I ever saw them) and most brilliant at the apex. The angle of inclination of the striae corresponded seemingly with the angle of the dipping-needle." At 9pm three irregular auroral bands from S.E. to N.W. 20°, 30° and 40° respectively above the southern horizon; and at midnight a bright curtain arch, 15° above northern horizon, from N.W. to N.E., and a faint curtain arch 15° above southern horizon from S.W. to S.E. Moon 2° S. Full moon
