band (brightness 1 to 2) ran from the 11. through Hercules, Corona Borcalis, and Cain's Venntici 

 to Leo Minor, with a patch of the same character in tlie WNW. from Orion through Auriga. At 

 12.15 there were taint traces of aurora in the KSK. and S. At 1 p. in. traces of streamers appeared 

 through Aquila, Lyra, I'rsa .Major, and Hoiites. The last faint traces \vere seen at 1.17 i>. in. A

January 20 and 27, 10.1.") p. >. to 12.15 p. in. At 10.15 p. in. there uas a faint and narrow ard> 

 in the NK. through Canis Minor, Cancer, Leo Minor, Coma Berenices Canes Ycnatici, and Ilootes. 

 A' 11.15 this was broken up into a hazy mass in Canis Minor, Cancer, and Leo, and streamers in 

 Seipcns and Bootes, and at 12.15 was reduced to a faint Hush in the NK. At 1 a. in. there were 

 two bands of short; ill-defined streamers in the NK., the upper from Hercules in the NNW. through 

 Corona Borealis, Bootes, and Canes Venatici, and the lower through Leo (p and fi) and Coma Be- 

 veirices, starting in Hydra and ending near Bootes (brightness to 1). These bands were 

 essentially unchanged at 1.15, but a bunch of streamers had developed at the NNW. end reaching 

 up into Draco. At 2 a. in. nothing remained but traces of the bands. These traces wore better 

 defined at 2.15, and there was a twisted streak (brightness 1) from close to n Vnlpecuhe. (NNW.) 

 through Cygnns (/? and S}. At 3 a narrow arched and somewhat sinuous band (brightness 1) 

 extended from NNW. in Vulpecnhi to KSE. in Hydra, through Cygnns (fi) a Lyne. Draco, the. 

 top of Bootes, Canes Venatici (), and Leo (d an<l It). At 3.15 this band was paler and formed an 

 outlying band of a zone with the same starting points. The western edge of the >:one ran through 

 Leo, Gemini, Auriga, Terseus, Andromeda, and Pegasus, and the eastern through Leo, Leo Minor, 



i Major, Camelopardalis, Ursa Minor, Cepheus, and Cygnns, while there was an arched band 

 low in the K. from ft Leonis to a Bootes. At 4 a. in. there was a liaxy /one (brightness to 1 ) with 

 ils starting points in the KSK. in Crater and NW. below C Pegasi. The western edge ran thiough 

 Leo. Leo Minor, Lynx, Camelopardalis, Cassiopeia, and Andromt da, and the eastern through Leo, 

 Cancer, Ciemini, the top of Orion, Taurus (rr), and Aries. At 4.15 the /one was in nearly the same 

 place, but its eastern edge had moved four or five degrees "W., while a twisted streak < brightness 

 2 to .'!) very sinuous and tinged with green and rose, began to move up from the KSK.. spreading 

 out and beginning to wave, at tirst slowly and then rapidly, as it approached the x.enith. passing 

 up through Ursa Major and Cassiopeia (where it stopped) in 2 or 3 minutes, while the zone faded. 

 It was brightest near the hori/.on. At 4.17 and 4.18 a second similar band was beginning to de- 

 velop a little to the K. of this. At 5.15 a belt of quiet bands ran from 1 ogasus through (. irerta, 

 Cygnus. Cepheus. Draco. 1'rsa Major, and Coma Berenices, while the lower edge passed through 

 C,;, gnus, Lyra, Sagitta, Hercules, Corona Borealis, Sc-rpens, and Boiites (brightness 1 to -',. Only 

 traces remained at 0.15. At 7.15 there were two bands (brightness to 1), one through Taurus, 

 Perseus, Cassiopeia, Cepheus, Cygnus, and Corona Borealis, and the other through (Vj'heus, 

 Draco, I'rsa Major, and Coma Berenices. At 8.15 a quiet band (brightness to 1) ran through 

 Vulpecu'.a, Hercules, Serpens. and Boiites. At 9.15 this was reduced to a streak, lying only in 

 Hercules and Corona Borealis, with faint traces in the NW. At 10. 15 a broad irregular mass of 

 rays, converging towards the y.enith (brightness 4), occupied Cassiopeia, Cepheus, Ursa Minor, 

 Camelopardalis. Ursa- .Major, Draco, Canes Venatici, Coma Berenices, Hoiites, and Serpens. This 

 body of rays was slightly tinged with green and rose, and vibrated easterly, having also a slow but 

 constant change of form and position. The western sky was tilled with long, line streamers from 

 ( 'aiiis Minor to Aries, and there was also a diffuse, white, quiet arch from the SK. to the N W.. with 

 its crown at an altitude .of about 10 above the southern horizon (brightness to 1). At 11.15 

 time was a broad striated, band (brightness to 1) running ESK. and WNW. through Hercules, 

 Ci.rona r.orealis, I'rsa Major, I'rsa Minor, Lynx. Aquila, and Gemini, white and quiet. At 12.15 

 tin re were very faint traces of an arch running KSK. by WN W., passing a little south of the /.enith. 

 A magnetic disturbance commenced at 4 a. in. and continued about ten hours, being at no time 

 very large, but reaching its maximum at 11 a. in.
