fifth or fixth Magnitude, and at this Day is to be feen as 
fuch in 9 s . i8°. 38'. A i ma T, with 55 0 . 29'. North Lat. 
A fifth New Star was firft feen and obferved by Heve- 
lius in the Year 1670, on July 1 5. ft. vet. as a Star of the 
third Magnitude, but by the Beginning of Ofioberw as 
fcarce to be perceived by the naked Eye. In April fol- 
lowing it was again as bright as before, or rather greater 
than of the third Magnitude, yet wholly difappeared a- 
bouc the middle of Auguft. The next Year, in March 1672. 
it was feen again, but not exceeding the fixth Magnitude: 
fince when it has been no further vifible, though we have 
frequently fought for its Return ; its place is 9 s . 3 0 . 17'. 
a i ma r.and has Lac. North. 47 0 . 28'. 
The Sixth and laft is that we defcribed from the Acfa 
Berolinenfia , in No. 343 ofthefe Tranfa&ions ; difcovered 
by Mr G. Kirch in the Year 1686, and its Period deter- 
mined to be of 404 f Days: and though it rarely exceed 
the fifth Magnitude, yetis it very regular in its Returns, 
as we found in the year 1714. Since then vvehave watched, 
as the Abfence of the Moon and the Clearnefs of Weather 
would permit, to catch the firft beginning of its Appea- 
rance in a Six* Foot Tube, that bearing a very great Ap* 
perture difcovers moft minute Stars. And on June iy. 
laft, it was firft perceived like one of the very leaft Telef- 
copical Stars ; but in the reft of that Month and July it 
gradually encreafed,fo as to become in Auguft vifible to the 
naked Eye; and fo it continued all the Month of Septem- 
ber. After that it again died away by degrees, and on 
the 8th of December at Night was fcarce difcernible by the 
Tube, and as near as could be gueffed, equal to what it was - 
at its firft Appearance on June 1 $th: lo that thisYear it has 
been feen in all near Six Months, which is but little lefs 
than half its Period : And the middle, and confequently 
the greateft Brightnefs, falls about the 10 th of September . 
Thofe that pleafe to feek for it, may expeeftits firft Ap- 
pearance in July next, and find it in 9 s . 6° 30'. circiter 
a t* 3 #. V, with Lat. Bor. 52°. 40'. II.
