192 MR. JOSEPH BAXENDELL ON THE 



September 21, 3IA. p.m. The spots in 6 have increased 

 in size and number. The spots in J are larger, and the 

 principal of following sub-group is rather larger than that 

 of preceding sub-group. The spots in e and H have 

 changed considerably, and the leaders in both are again 

 decidedly larger than any of the other spots in the groups. 



September 22, gh. a.m. There seems to have been a 

 movement of rotation in preceding large spot of J since 

 yesterday afternoon. 



September 24, gh. a.m. Preceding large spot of J 

 appears to have gone round three quarters of a revolution 

 since gh. a.m. September 22nd. The rotation, if real, has 

 been in the direction E.N.W.S. as seen from the earth, or 

 to a spectator on the surface of the sun E. S.W.N,, the 

 spot being in the iiorthern hemisphere. There seems to 

 have been little or no movement in the large spot of 

 following sub-group. 



September 25, iih. a.m. 6 approaching western limb, 

 and large spot of preceding sub-group is now much larger 

 than any other in the group. The following sub-group 

 contains more spots than the preceding. The position of 

 the longer axis of principal spot of J seems to have altered 

 again, and in the same direction. A gth mag. spot has 

 broken out at f, far removed from any other spot. 3IA. 

 p.m. The distance between the centres of the principal 

 spots of the sub-groups of J is 3' 29.4", or more than 

 96,000 miles. 



September 26, ^h. p.m. Preceding large spot of J 

 appears to have rotated through an angle of about 30° 

 since yesterday forenoon, and in the same direction as 

 before. The large spot in following sub-group seems to 

 have moved very little, and if at all it has been in a con- 

 trary direction. The spot f has increased, and I am pretty 

 sure I caught sight of a minute companion at a distance 

 on the following side.
