The aneroid was moved from the outside of the cabin bulkhead to a place on the fore and aft bulkhead 
in the cabin near the starboard door on account of the thermometer attached which is not graduated 
below 10°.

Com. and until 4am
Moderate breezes from S.S.W. and snowing at times. At 1.50 a meteor was seen about 1/4 of a mile from 
the ship in the S.W. quarter of the horizon. It was very brilliant and remained in sight for about 7 minutes 
appearing like a ball of fire.* At 3 the weather cleared. There was a fine aurora during watch.

*Editor's note: DeLong gave a more detailed description of the phenomenon in his own diary:
"At 1.50am a very curious electric phenomenon was observed. A ball of electric light formed about one 
quarter mile from the ship on the surface of the floe (in size about that of ' a barrel', according to Mr. 
Dunbar), throwing out rays in all directions, and slowly rose and worked away from the ship, decreasing 
in size and brilliancy. When almost extinct it advanced again, increasing in brilliancy, and, descending to 
the floe, disappeared. This occurred twice in seven minutes. The appearance of the electric ball was 
preceded by a fine aurora."
