| TOK 290 | We count 2MASS J13313493+5857171 as single close in, although its PSF | |
| appears somewhat extended in the 2009.13 epoch. However, it is a | ||
| likely companion to the nearby G2-star HD 117845 at 11" separation. | ||
| HD 117845 has been included in the AstraLux field and appears to be | ||
| itself a close binary with a ~0.5" separation. | Jnn2012 | |
| AB: A is SB, no SB orbit. X-ray source. | Tok2014d |
