Miles. At 4.20 there was a brighter arch (brightness 1 to '2) from the E. to N. through Hercules, 

 Draco, Cepheus, Cassiopeia and Andromeda, with traces in Perseus, Aries, Corona Borealis, Ursa 

 Major and Lynx. At 5.15 to 5.20 a broad band, waving slowly, ran from Auriga through Camel- 

 <;p:irdalis, 1'rsa Minor, Cassiopeia, Cephens, Lacerta, Cyguus, Lyra and Hercules (brightness 1 

 to '2). At (i.17 there was a broad curtain (brightness 2 to 3) from .Sagitta in the E. through Cygnus 

 and Cassiopeia, with streamers ceuteriug towards the y.enith, and a broad band from the northern 

 extremity of the curtain to Ursa Major, with a slight vibration. At 7.15 to 7.20 a quiet band 

 (brightness l)ran from Leo through Coma Berenices and Bootes. The last aurora seen \vasa 

 quiet arch (brightness to 1) at 8.17 in the SW., from SB. to NW., reaching an altitude of about 

 25. Then' was a magnetic disturbance, affecting almost solely the horizontal force, between ~> 

 and (! a. in., reaching its maximum about 5.30. 



Mni'ch 10, 1883, 1 a. m. io 9.1 7 a. m. At 1 a. in. there was an arch in the NE. (brightness (I to 1) 

 with one end near the horizon ESE. and the other in the twilight NNW., running just above a Bootis, 

 Corona IJorealis and Lyra (ft). At 1.15 this was rising rapidly and soon formed a narrow zone 

 across the zenith, again narrowing into a sinuous band (brightness 1) through Leo (a), Lynx, 

 Camelopardalis, Cassiopeia and Andromeda. At 2 a. in. there was a broad zone with its starting 

 points ESE. in Virgo and NNW. in Andromeda, extending in breadth from ft Tauri in the S\V., 

 to ;/ Ursa,- Majoris in the NE. The western band was the brightest reaching brightness 2, while 

 the rest was pale and hazy (brightness to 1). At 2.15 to 2.20 the ESE. starting point had spun 

 out over about 20 in azimuth, forming a broad patch of very sinuous and, as it were, curdled 

 streamers, while the eastern edge passed through Bootes, Corona Borealis, Hercules, Lyra (ft) and 

 Cygnus (e). The whole /one was rather broken and not so bright (brightness 1 to 2). At 3 a. in. 

 it had all faded to traces except the easternmost baud, which ran through Hercules, ft Lyra- and 

 e Cygni, and was still paler at 3.15 to 3.20. At 4 a. in. there was no aurora, but at 4.40 faint traces 

 appeared in the NW., developing into a very transitory band across the zenith from NW. to SE. 

 No more was seen till 9.17 a. in. when there were faint traces in the NW. The needles were some- 

 what agitated at the time of the aurora without any larger disturbance. 



March 17, 1883, 3.15 . HI. to 9.20 a. m. At 3.15 to 3.20 there was a faint, arched streak from 

 near the horizon ESE. in Virgo up through a Corona Borealis. This soon rose and formed a zone, 

 which from 4 to 4.20 had a brightness 1 to 2, starting ESE. in Virgo, and XNW. in Andromeda, 

 occupying Bootes, Canes Vcnatici, Ursa Major, Cameleopardalis, Auriga and Perseus. It was 

 very sinuous in the ESE., shifting and changing form and brightness, and rather yellow in color. 

 At 5.15 to 5.20 it had faded to a band (brightness to 1) from Orion through Gemini, Lynx, Ursa 

 Major,' Canes Venatici and Bootes. At 6.15 to 0.20 a quiet zone (brightness 1) crossed the zenith 

 from AVXYV. to ESE., from Taurus through Auriga, Gemini, Lynx, Camelopardalis, Ursa Minor, 

 Draco and Hercules. There were traces only at 7.15 to 7.20 a little south of the zenith. No more 

 was seen till 9.20 when there were traces of an arch from SE. to NYV., through Corona Borealis, 

 Ursa Major, Lynx and Auriga. The magnets were unusually quiet all night. 



Micrch 18, 18S3, 4.10 a. m. to 9.17 <t. m. At 4.40 a. m. (11.30 p. m. local) a very faint, narrow 

 band stretched across the zenith from ESE. to XW., through Ursa, Major, Camelopardalis, Auriga, 

 and IVrseus indistinct towards the horizon. At 5 to 5.20 there was a rather indistinct short band 

 in the EXE. from Hercules to Lyra. At 7 to 7.20 a slowly waving band (brightness to 1) ran 

 from Leo through Coma Berenices, Bootes, and Serpens. At 8 to 8.20 a band of streamers waving 

 slowly like a curtain from E. to "\V. ran from Persons through Cassiopeia, Andromeda, Lacerta, 

 and Cygnus. and two quiet bands nearly parallel extended from Aquila through Hercules, Corona 

 I'.o-ealis, P.ix'ites, Canes Venatici, Ursa Major, and Leo (brightness of all 1 to 2). At 9.17 there 

 were traces in the W. The magnets were slightly disturbed from 8 to 9 a. m. 



Min-ch in. iss:',. .1.40 a. in. i<> G.L'O . >n. At 4.40 a pale band (brightness to 1) could be seen 

 crossing the. zenith with its extremities some distance from the horizon ESE. and NW., passing 

 through P.oiites. Canes Venatici, Ursa Major. Camelopardalis, and .Perseus. At 5 to 5.20 a similar 

 band passed west of the zenith from Serpens through Bootes, Coma Berenices, and Leo. At G to 

 li.20 a band of streamers in rapid vibration (brightness 1 ) ran from Orion through Taurus. Perseus, 

 Andromeda, Cassiopeia, Lacerta, and Cygiius. The needles wen; slightly agitated at the time of 

 the aurora
