B 2550 BD+49 440 (8.5) and 441 (9.0) are together in a high power field. Both
are close pairs; brighter star is deep orange, the fainter (ADS 1341,
HU 1210) is white. At present the brighter star is the easier pair,
but as its duplicity was missed by Hussey, Aitken, and van Biesbroeck,
then they measured CD, it must have opened out more recently. B__1963b
