82 Governor Hennessy's Observations on the [Recess, 



spot was surrounded by a penumbra stretching towards the centre of the 

 sun, the second spot was small and sharply defined, the third spot, or 

 group of spots, had a penumbra, and the fourth spot was surrounded by 

 a space of very brilliant light. 



These spots I subsequently refer to as Nos. 1, 2, 3, and 4. 



Moving with the rotation of the sun, the line of spots gradually became 

 horizontal, and at 12 o'clock (noon) they lay thus (see fig. 1). 



Fig. 1. 



At 15 seconds past 12 o'clock the first contact of the moon took place 

 at the point marked A. At 12* 24 m 20 s, 2 the contact was observed of 

 the moon with the penumbra of spot No. 1. 



At 12 h 25 m 25 s -5 contact with left of No. 1 spot. 



At 12 h 26 m 58 s the spot was completely covered. 



During all this time no vibrations or change of any kind was noticed in 

 the magnetic needle. 



At 12 h 44™ 15 s the moon's limb had advanced to the sun's centre. 



At l h 10 m 47 s - 5 spot No. 2 was passed, and at l h 18 m 6 s spot. No. 3 

 was passed. 



All this time not the smallest magnetic change could be noticed. 



At l h 27 m 22 s the total eclipse took place, and lasted for 6 minutes and 

 13 seconds ; the first appearance of the sun's limb from behind the moon 

 being at l h 33 m 35 s . 



The spots reappeared as follows : — 



No. 1 at l h 41 m 12 s 



2 „ 2 33 14 



3 „ 2 39 48

and at 2 h 52 m 39 s- 8 the last contact of the edge of the sun and moon was 

 noticed. 



During the 6 m and 1 3 s of total eclipse not the slightest change of any 

 kind could be observed in the magnetic needle, nor did it move or vibrate 

 in any way on the appearance of the solar spots.
