Abstract
VARIABLE STARS.—The two following stars require further examination, as affording signs of fluctuating brightness, (1) Lalande 23228–9, estimated 7th magnitude, 1795 May 8, and 51/2, 1798 March 14. It is 67 in Lamont (No. 1149), and in Steinheil's Chart, one of the series published by the Berlin Academy, it is only 8th mag. Neither Bessel nor Santini has observed it. (2) The star Lalande 27095, in Boötes, 7th mag., observed 1795 May 25, and missed by Olbers, 1804 March 22, during his observations of the comet of that year: it is the star which passed the centre wire at 14h. 42m. 10s. (Histoire Céleste, p. 164), and Olbers distinctly says of it “ist nicht mehr am Himmel zu finden.” It was, however, observed by Bessel in his Zone 415, 1828 May 24, as a 9th magnitude; it is 9.0 in the “Durchmusterung,” and is called 9.1, 1866 June 5, in the Bonn Observations, vol. vi. The positions of these stars for 1875.0 are:—
