Light curve

HE 1029-1401 is a bright quasar in Hydra, close to the constellation Crater. At the time of the discovery, HE 1029-1401 was one of the 3 optically brightest quasars in the heavens, and the brightest quasar ever discovered in the optical! No question: HE 1029-1401 is the brightest radio-quiet QSO in the southern sky.
HE 1029-1401 was discovered in the 1980s by the Edinburgh-Cape Blue Object Survey (EC) with the UK-Schmidt Telescope at the Anglo Australian Observatory (AAO). The designation HE 1029-1401 refers to the Hamburg/ESO Survey of Bright Quasars (HE), where this object was finally confirmed as a quasar in 1990. This quasar resides in a very luminous type E1 elliptical host, which shows signs of an advanced stage of merger with a highly disturbed companion galaxy.

HE 1029-1401 is a small amplitude variable quasar with a total variability of about 1 magnitude, ranging between 13.6 mv and 14.4 mv. No data on significant optical variability have been published to date.
Observations by the Frankfurt Quasar Monitoring programme have confirmed an optical variability ranging between 13.8-14.4 mv, very close to the data from the literature. HE 1029-1401 appears stellar for both CCD cameras and visual observers with telescopes of 8- to 10-inch of aperture and larger. CCD observers, as well as visual observers, shall use the comparison stars given above.


When observing quasar HE 1029-1401, do not forget to visit bright planetary nebula NGC 3242, about 4.6° to the south. NGC 3242 is dubbed the "Ghost of Jupiter", due to its remarkable greenish-blue colour.
Variable star observers may like to take a look at bright variable U Hya (4m.7-6m.2), only 1.6° NE of the quasar. U:Hya is a carbon star with particularly reddish color during minimum brightness - a nice catch for small telescopes.
