[vsnet-alert 13697] Re: Unknown type variable star in Perseus = TCP J04283707+3157578

[Korotkiy Stas]

This object is not so much blue as can be seen on the sky-map.org as there used DSS2 plate,
where object is visible only on the blue plate taken 1/10/1992, and the red plate (11/24/1989) object is not visible.
Plates DSS1 shot in one night (22/10/1955), it is clear that the object is white, or even slightly bluish.
All this is well seen on this link: http://goo.gl/rRV6n
