Subject: 1RXP J113123+4322.5: a quiescent counterpart Examining the Pejcha's image (vsnet-campaign-dn 2150) and the Kyoto images (vsnet-alert 7228), it is revealed that the outbursting object is the northern star of the pair, not the southern star as suggested on vsnet-alert 7224. The precise astrometry with Kyoto images is in progress. Checking the DSS images, this northern star is rather blue, besides the southern star is red (vsnet-alert 7225). The northern one (2MASS position = 11:31:22.39, +43:22:38.4) is likely a quiesient counterpart of 1RXP J113123+4322.5. Sincerely Yours, Hitoshi Yamaoka, Kyushu Univ., Japan yamaoka@rc.kyushu-u.ac.jp
