Feb. 28, 1885. — Solar corona seen by Mr Kankin 
from Plateau of Storms at about 16 h 15 m . Pormed on 
scud. Colours as in diagram. Outside these portions 
of circles were seen flashing for a short time, but 
their colour was not determined. 
March 1, 1885. — At 3 h lunar corona ; colours as in 
diagram. Formed on scud. Eadius of inner red 
= 3° 18' ; radius of outer red = 4° 49'. Solar halo 
at 14 h 23 m ; faint red inside; radius by steph. about 
18°.

March 21, 1885. — At 20 h lunar halo observed. Eadius by 
stephanome = 23° 15'. 
March 22, 1885. — At 20 h double lunar corona; 
colours as in diagram. Eadius of inner red, 1° 53'; 
radius of outer red, 4° 40'. It was formed on passing 
cloud, but when the sky was clear a faint blue glare 
surrounded the moon. 
March 30, 1885. — At 2 2 h lunar halo on cirrus clouds. Eadius 
by stephanome = 1 8°. 
April 8, 1885. — Solar halo at 10 h and ll h . Eed inside. Eadius 
by stephanome (doubtful observation), 25° 50'. At ll 11 the top 
and bottom of this halo were brighter than the sides. 
April 17, 1885. — At 6 h faint solar halo, which vanished at 
6 h 10 m , except two very bright spots with red towards sun, one on 
each side of sun, and at the same height above the horizon. 
Eadius by stephanome, 24°. At 7 h faint halo was again observed; 
at 8 h the highest part appeared brightest, and at 9 h only that part 
remained visible. At 13 h the halo was again visible, and five 
measurements were made as under : — 
1st radius = 22° 45' 
2nd „ = 23° 40' 
3rd „ = 22° 15' 
4th „ = 23° 0' 
5th „ = 22° 15' 
To inside of red ring.
