See a star move!
Compare between the DECaLS and the SDSS image in http://legacysurvey.org/viewer?ra=164.1046&dec=7.0040&zoom=14&layer=decals-dr2
SDSS in 2002, triangle shows position in 2013
DECaLS in 2013
http://skyserver.sdss.org/dr12/en/tools/explore/Summary.aspx?id=1237658423555653642
center of triangle indicates postion in 2013
Wolfe 359 Wolfe359 moves about 4.7 arc-sec / year, so in about 10 years it should move about 50 arc-sec
It looks as if it has moved 50" (50 arc-sec) in the image, so good agreement.
NED
GJ 0406 10h56m28.4s +07d00m47s !V*
CN Leo 10h56m28.4s +07d00m47s V*
!V* must mean a flare star that sometimes emits X-rays.

Only a few stars that are "close" to us show movement like this. All stars move, but the movement is tiny.
It has a redshift z(~) 0.000043 , so it is moving away from us.

The star moved during the 5 years of study.
