Mr, Pigott’s Obfervations m 
53 Serpentis. 
In 1784 I perceived that this ftar was miffing; nor was 
vifible in 1785 with a night-glafs. 
A ftar marked by Bayer near e Urfa? Minoris. 
Cassini could not fee this ftar. In 1782 I took, with a 
night-glafs, a plan of all the ftars near its place, and near, 
the £, none of which were brighter than the 7 . 8th magni- 
tude. I have fince re-examined the plan, but found no alte- 
ratioin 
The or Ptol. andUL. Beigh’s 14th Ophiuchi or Flam— 
steed’s 36th. 
I have no doubt but that this is the ftar which is faid to^ 
have difappeared before 1695. It is alfo evident, by what' 
Hevelius fays in his Catalogue on the 6 and B, : that the ^ 
was not feen by him. In 1784 and 1785 I found it of the 
4 . 5th magnitude, much brighter than 39, alfo rather 
brighter than 51 and 5 S', and lefs than 44. On the 30th of 
June, 1783, I have marked it in my joumabequal to 39, and 
lefs than 51 and 5.8$ but as the obfervation was not repeated,. 
I am far from being certain it has undergone any change, par- 
ticularly as this ftar has a fouthern declination of 26°, and 
therefore great attention rauft be given to the ftate of the:- 
atmofphere,.
