    Large Proper Motion    

This page introduces some of the stars with large proper motion, found in the amateur images offered to the MISAO Project.

Because the position of a star with large proper motion is different from the cataloged position in the USNO-A2.0, etc., it will be marked up as red after the examination using the PIXY System 2. You can see the proper motion easily comparing with the DSS images, even in case of the amateur images.

The image size is about 6 arcmin.

o LHS 1794 = G100-44

R.A. 05h53m14s.04  Decl. +24o15'31".9  9.59 mag

o G104-51

R.A. 06h38m52s.61  Decl. +22o55'15".9  11.83 mag

o G88-12

R.A. 07h13m13s.84  Decl. +24o06'29".4  10.16 mag

o LHS 1053 = G171-44

R.A. 00h17m06s.49  Decl. +40o56'53".0  8.61 mag

o G209-26

R.A. 20h21m12s.24  Decl. +46o27'16".2  11.20 mag

o LHS 524 = G215-50

R.A. 22h29m49s.09  Decl. +41o28'49".1  11.52 mag

    Double Variable Star with Large Proper Motion    

o LHS 3 = GX And & LHS 4 = GQ And

LHS 3 = GX And  R.A. 00h18m23s.12  Decl. +44o01'23".2  7.83 mag
LHS 4 = GQ And  R.A. 00h18m26s.06  Decl. +44o01'38".8  9.31 mag

Francisco Manuel Rica Romero told me that this pair is designated as GRB 34 AB, a orbital double star with a period of 2600 years.

The image size is about 8.5 arcmin.

    Based on photographic data of the National Geographic Society -- Palomar
    Observatory Sky Survey (NGS-POSS) obtained using the Oschin Telescope on
    Palomar Mountain.  The NGS-POSS was funded by a grant from the National
    Geographic Society to the California Institute of Technology.  The
    plates were processed into the present compressed digital form with

    Telescope Science Institute under US Government grant NAG W-2166.
