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.

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.
- The left side images are the DSS (Digitized Sky Survey) images obtained at the following site.
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
their permission. The Digitized Sky Survey was produced at the Space
Telescope Science Institute under US Government grant NAG W-2166.
