Note: Whenever only an ingress or egress are observed the UTmid is determined using an assumed length (with appropriate SE).

Transit Light Curves






Great LC considering the high air mass, lightning that terminated observations and use of a portable 10-inch telescope at a remote site.

Out-of-Transit Light Curves



The discovery paper by Mandushev et al includes LCs showing depth = 10.8 mmag (z' and B-bands) with a length of ~3.5 to 3.6 hr (depending on definition used).
