Abstract

Cen X-4 is a neutron star X-ray transient discovered in 1979 during an outburst. It has since been in quiescence for almost 41 years. Recently, ATel #14254 indicated that Cen X-4 might enter an outburst in the near future, based on a gradual, significant, optical brightening detected in the long term (12 years) optical monitoring of the source with the Las Cumbres Observatory (LCO) 2-m and 1-m robotic telescopes.
