that its intensity and geometry are very similar to the large-scale solar magnetic field. The estimated period for the activity cycle of 18 Scorpii is about seven years, which is significantly shorter than the Sun's, and its overall chromospheric activity level is noticeably higher. Like the Sun, it has a hot corona with a temperature in the range of 1.5-2 MK and an X-ray luminosity of 8 ± 1.5 ergs s^-1.

Though 18 Scorpii is only slightly
