A little ramble through 19th century astronomy - Lalande 27095 Bootes in 1804

 Nature May 18th 1876

The star Lalande 27095 (Bootes)

Olbers, writing to Bode in July 1804, respecting his observations of the comet of that year, remarks of Lalande 27095, near the place of which star the comet was situated on March 22nd: It was observed by Lalande as a seventh magnitude on May 25th 1795 (Histoire Celeste, p 164).

The star was observed by Bessel on May 21st 1828 as a ninth magnitude and is No. 976 of hour xiv in Weisse’s second catalogue. In the Durchmusterung it is magnitude 9.0.

There is evidently reason  for supposing the star to be variable.
