The nearby star CN Leonis
Images of the nearby, variable star CN Leonis, in which a coronal emission line has been observed with the UVES spectrograph at the 8.2-m VLT KUEYEN telescope. This star is relatively nearby (8 light-years) and moves about 5 arcsec/yr in the sky, approximately towards south-west (the 4 o''clock direction). The motion is clearly visible on these two images obtained with the UK Schmidt telescope and reproduced from the Digized Sky Survey 2; the blue image (left) was taken several years before the red one (right). Moreover, the red colour of the star is obvious; the red image is clearly brighter than the blue one. The field measures 5 x 5 arcmin 2 ; North is up and East is left.
