AW Lacertae / AW Lac
Light curve and phase diagram of the EB type eclipsing binary AW Lacertae / AW Lac. These were constructed from photometry of 62 images taken with the Bradford Robotic Telescope Cluster Camera (BRT), through a tri-colour green filter, between 2014 July 10 and 2016 January 8.
On 2019 November 29/30 I observed a primary minimum from Somerby Observatory with the 2 inch Titan. The 225 images were unfiltered.
The time of this primary minimum, as calculated by Peranso, is HJD2458817.377690 +- 0.000126
A secondary minimum was observed on 2020 January 20 from Somerby Observatory with the 2 inch Titan. The 161 images were unfiltered.
The time of this secondary minimum was calculated by Peranso to be HJD2458869.380172+-0.000231
Combining all the above results generated the following light curve and phase diagram. The observations were not transformed.
The catalogue period for this star is given as 1.1428498d (GCVS, AAVSO VSX) and 1.1428640d (Kreiner). There is o-c activity with this star (Kreiner). (Accessed 2020 January 22.)
