294 SOLAR SPOTS OBSERVEB AT TORONTO, 



were tlie Faculse so well seen as yesterday — tlie Penumbra fainter to- 

 day, probably on account of haze in tbe atmosphere. 



January 22nd, l2°-20', apparent time. Definition good, with a 

 slight haze — Penumbra darker to-day — the Nucleus has broken up 

 into four portions, with some smaller spots towards the limb and centre 

 of the Sun — the general shade of the Southern part of the Penumbra 

 darker than the Northern part — a faint Penumbra round small dark 

 spot near the limb — very strongly defined Faculse seen close to the 

 opposite or north-western limb — observed granular appearance of the 

 body of the Sun. 



January 2Ai\\, 12°-15', apparent time. Main body of Nucleus has 

 nearly separated from the other parts, and formed a distinct spot sur- 

 rounded by a Penumbra — there being three small Nuclei separating 

 the larger spot from the other two — one of the spots seen on the 22nd 

 having either disappeared or merged into the others — the Penumbra 

 smaller at the part between the principal spot and the others, shewing 

 a tendency to isolate the principal spot — Faculse on opposite limb very 

 brilliant and strongly defined — definition very good — Sun's disc gran- 

 ular — Penumbra generally darker than previously observed — no other 

 spots visible on this or on previous days, besides those referred to. 



January 25th. Cloudy, and no observation. 



January 26th, l°-30' apparent time. The separation between 

 the principal spot and the others complete — the Nucleus of the prin- 

 cipal spot extending to the edge of the Penumbra, on the side towards 

 the Sun's north-eastern limb — one portion of the Penumbra round 

 the spots nearest the limb, very much more brilliant than the other 

 parts — Penumbra much striated round Eastern spots — a small spot to 

 the South of the ones nearest the limb, with cloudy looking streaks 

 between it and the Penumbra, not exactly Penumbra, but more resem- 

 bling cirrhous clouds — about ten or eleven new spots observed on the 

 south-eastern limb, not far removed from the Equatorial regions of 

 the Sun, a faint Penumbra apparently round one of them — strongly 

 marked Faculse around these new spots. The spots originally ob- 

 served are approaching the western limb, having, I consider, passed 

 the centre of the Sun about the 24th instant. 



I may here observe that the Telescope used was an Equatorial Re- 

 fractor of excellent quality, made by Henry Fitz of New York, of sixty- 

 two and a half inches focal length, and a clear aperture of four and half 

 inches, very firmly mounted, surrounded by a circular wooden build- 

 ing, Avith a revolving dome ; the eye-piece used was a positive or
