Atlas. If we view the
handle as a small 'Dipper'
this star lies at the end of the handle. The wide mag 5 companion 28 or
BU or Pleione can be spotted with the unaided eye and is easy with any
optical aid.
In the 25X100 the stars appear as Yellow and
Whitish. Struve discovered
a close companion to 27 in 1827 which Yale Cat. gives as .6" sep but I
have no other details.

The double 27 + BU (or
27+28 Tau) is located on
the eastern edge of the Pleiades about 25' east of Alcyone. The
Pleiades
is truely one of the great targets for binoculars. It is a very
wide
double and is easily visible. Tonight I could easily see the 8
brightest
stars of the Pleiades but anything else was a struggle because of
a high haze and the Portland light bubble.
primary....blue-white tending to white companion...yellow-white

This pair is actually 27 + 28
Tau, or Atlas and Pleione
(as has been said before). I got the feeling that the PA should be just
the other way around. The table says : 180, but isn't it 0 (or checking
Skymap : 2)?

Ah, a mystery. Sep. seems
correct as compared with
previous
obs, but PA seems wrong. Should be near 0°, not 180°. Given that there is no other star of this mag around 180°, I assume either the comp. is quite variable, or that the measure was measured in wrong quad. Is BU 28 Tau?
