We employ daily Yohkoh SXT full disk images and National Solar Observatory/Kitt Peak (NSO/KP) photospheric magnetograms from 1993–1999 to study the solar cycle variation of X-ray bright points (XBP) and magnetic bipoles (BP). The XBP number follows a well-known anti-cycle variation, but the BP number does not. We see this as a clear indication that the anti-cycle variation of XBP number is an apparent, not a real effect.
