A star missed by Flamsteed in Cancer

 

Roughly half way between the stars beta cancer magnitude 3.5 and delta hydra magnitude 4.2 is an unmarked star on star atlas 2000. Another one that was not listed by Flamsteed.




This star turns out to be HD 71115 a mag 5.1 star which is listed in sky catalogue 2000. Its a double star. Depending which double star catalogue you look at the two components stars are of

mags 5.1 and 9.2 in catalogue 2000

mags5.2 and 10.0 in Washington Double Star Catalogue

mags 5.5 and 9.5 in Burnhams

Its amazing just how many bright easy to see naked eye stars just have not been noted by Flamsteed.
