V728 Scorpii

It was discovered on 4 October 1862 by John Tebbutt, an astronomer living in New South Wales, Australia, while observing a comet.

[4] At the time of its discovery, the nova had an apparent magnitude of 5, making it visible to the unaided eye.

[5] Tappert et al. conducted an observing program from 2009 to 2011 to investigate nova candidates.

Using photometric and spectroscopic observations, they identified the post-nova star corresponding to Nova Scorpii 1862.

They reported that the spectrum resembled that of a dwarf nova with a high orbital inclination, suggesting that it might be an eclipsing variable.

A visual band light curve for V728 Scorpii. The main plot shows the long-term variation with arrows pointing to the stunted outbursts which occur every ~30 days. The inset plot shows the variation caused by the eclipses. Adapted from Vogt et al. (2018) [ 6 ] and Tappert et al. (2013). [ 7 ]
