NOTES ACCOMPANYING DECLINATION RECORDS AT TEPUTZ BAY 



October, 1903. 4, auroral display about 9:30, fog prevailing since 0:00; 4:03:48, 

 daylight begins. 7:09: 24,* oscillation checked with steel pin; 7:09:46, scale passed off 

 thread, 4". 5 estimated; 7:10:36, oscillation checked with pin; 7:10:32, quiescent for 10 

 seconds. 12, snow drifting, cloudy, daylight about 6 A. M., bright moon makes it difficult 

 to determine daylight in cloudy weather. 14, slight aurora in east on beginning, sky 50 

 per cent clouded, windy ; 14: 07: oo, daylight begins ; 14: 20: 30, cloudy and foggy ; 14: 24: oo, 

 thick, cloudy weather. 15, cloudy and foggy entire period of observation. 16:21:00, 

 aurora appears ; 16: 21: 32, aurora disappears gradually overhead, low fog ; 16:21: 36, aurora 

 again appears extending from north to southwest, but not very intense ; 1 6: 22: 34, wind rising ; 

 16:22:58, aurora has disappeared. 18, on beginning light aurora from southeast to south- 

 west, clear and still ; 18:00:48, aurora has disappeared; 18:03:34, scale went from 4O a .8 to 

 42 a .5 in 30 seconds. 19, foggy; 19:09:13, scale traveled from 9:13 to 9:15 and then 

 stopped. 21, clear; 21:04: 12, clouded over; 21:07:00, daylight begins; 21: 16:06, daylight 

 ends ; 21: 18: 38 clouded entirely; 21: 20: 18, R. R. T. reports aurora in northwest. 22: 16: oo, 

 daylight ends, clear; 22:18:42, very high wind in gusts; 22:19:32, faint auroral light in 

 southwest. 23, observations omitted on account of blizzard. 25, foggy, clear overhead, 

 still; 25:03:10, very slowly increasing; 25:03:12, very slowly increasing; 25:03:24, wind 

 begins to rise; 25:04:00, partly cloudy; 25:07:00, daylight begins; 25:08:22, starts to 

 decrease; 25:08:40, continues to increase from 22 4 .2. 27, northeasterly storm; 27:14:26, 

 wind subsides; 27:15:00, wind rises. 28, cloudy and calm; 28:02:06, clouds breaking 

 away overhead, foggy; 28:03: 14, took 30 seconds to make oscillation ; 28:03: 50.5, took one 

 minute to make this oscillation beginning at 3:50; 28:07:34, daylight begins; 28:11:20, 

 cloudy and calm, light snowflakes ; 28:17:50, snowing. 29:18:00, clouded entirely. 

 30: 22: 30, overcast and cloudy. 



November, 1903. i : oo: oo, auroral light is waning as observer begins ; i : oo: 22, stopped 

 for an instant and continued to decrease ; r: oo: 28, clear sky, aurora has disappeared ; i : oo: 50, 

 aurora appears again, not very brilliant, clear sky; 1:01: 12, passed g'.o and came back to 

 recorded values, aurora not very brilliant from magnetic northeast to zenith and magnetic 

 southwest; 1:01:22, aurora growing faint in northeast and zenith, southwest remains the 

 same; i : 01 : 26, jumps off scale from 70*. 2; i : 01 : 38, brilliant light again northeast, zenith and 

 west; 1:01:58, aurora fainter and in southeast; 1:02:10, aurora mostly in north; 1:04:12, 

 a gradual change from 4:12 to 4:14.5; 1:07:10, aurora disappeared; 1:08:12, daylight 

 begins. 2:08:15, cloudy, completely overcast. 3:12:32, steady at 33m and begins to 

 decrease, no oscillation. 4:00:14, cloudy and snowing; 4:00:46, observations suspended 

 to give order relating to ice gain signals; 4:04:12, clear sky; 4:07:58, daylight begins; 

 4: 17: 12, faint aurora stretching in line overhead from magnetic northeast to southwest ; 

 4: 19:28, bright, moonlight night; 4:22:20, faint aurora from overhead to magnetic south- 

 west ; 4:22:44, aurora has disappeared. 5:16:00, thick fog prevails throughout observa- 

 tions. 8:00: 10, clear, light fog on horizon; 8:04: 12, clear, moonlight, still. 9:08: 22, magnet 

 had to be raised; 9:08:50, stationary for 10 seconds or more; 9:09:30, stationary for 10 

 seconds or more; 9:09:52, reaches 48 d .o at 9:53; 9:09:56, reaches 38*. 7 at 9:57.2. 

 11:00:34, reaches 7id at 0:34.5; 11:00:56, faint aurora in zenith; 11:01:42, reading 



*The first figure indicates day of month, the others the hour and minute on chronometer, civil reckoning 

 from o hour through 24 hours, thus : 23: 21:08 means 23d day of month at 2ih o8m or gh o8m P. M. Directions 

 unless ]otherwise"specified are magnetic.
