Not illustrated. 1863 edition. Excerpt: ...457. On the first day of observation exhibited very distinctly the deficiency of penumbra between two neighbouring nuclei, which formed one of the earliest peculiarities noticed by Dr. Wilson of Glasgow. The positions observed were at 1556.. 136.2.. 4-18.1 159-6.. 134-9. ]17'8 (mean) 162.5 I330 +i8 Diurnal motions--30' and zero... for lat. 4-i8. There is at the next rotation a dot (481) at 180-5.. 132.3.. +187 but the identity is very questionable. 459. A normal circular spot. at 155-6.. 99.3..-12.6 159-6.. 99-4..-12.7 162-5 995-J2'5 Diurnal motions +1' and zero.... for lat.--130. 465. Rather high north. Normal spot. at 159'53 25'3 +37'a 162-524.. 22-4.. +37-0 The first observation was taken near the limb, and there is no third one in the record. Diurnal motions--55'and--4'.... for lat. +3 70. 466. A nearly normal spot. at 162-5 94. +l3'1 166.5.. 10.4.. +12.8 Diurnal motions +15'and--4'.... for lat. +130. 470. A neat circular spot. at 173-6.. 306.8..-25-3 176.6.. 308-2..--26.0 The last observation was taken very near the limb, and as the resulting motions are con-tradictory, I do not put them down. 471. A dot first without and then with penumbra. at 166'6.. 298-6.. 4-16.0 173.6.. 299-8.. +15.6 476. Observed three times, but as one of two components disappears, no comparison of positions can be made. 479. A rather large circular spot. at 176-5.. i80-..--14-5 1805.. 180-3..--14'9 183.5 I80-i-147 Diurnal motions zero and zero.... for lat.--150. 485. A normal circular spot of 2 diameter. Diurnal motions--50' and + 6'.... for lat. + 29. 486. Another circular penumbral spot. 488. I disregard the influence of the small spots north-following. at 190.6.. 2-2.. +13.4 197-6.. 22.. +13.7 Diurnal motions zero and +3'.... for lat. + 13c 491. The dots...show more
