Dschubba (forehead) is the name for the star δ Scorpii (delta Scorpii). Dschubba normally has an apparent magnitude of 2.5 and belongs to the spectral type B0. Dschubba is approximately 402 light years from Earth.

Other spellings or names are Dzuba, Iclarcrau, Iclarkrav.

Because Dschubba is near the ecliptic it is occasionally occulted by the Moon, or (extremely rarely) by planets.

Variability

In June 2000, Delta Scorpii was observed by Sebastian Otero to be 0.1 magnitudes brighter than normal. Its brightness has varied since then and has reached as high as magnitude 1.6 or 1.7, altering the familiar appearance of Scorpius. As of 2005, the flare up is still continuing. Although the brightness varies, it remains well above its previous constant magnitude.
