In 2015 June, the symbiotic binary star AG Pegasi underwent a period of outburst. SkyCam T, mounted onboard the 2 m Liverpool Telescope, collected over 650 unfiltered images of this event, and several thousand images from before and after. This note presents Sloan r′ band light curves obtained from these images. In addition, a color–magnitude diagram (CMD) using AAVSO data is included to infer parameters of the system’s white dwarf (WD). Features in the light curve allow one to classify this outburst as that of classical (or Z And) type. The CMD suggests the temperature and luminosity of the WD increase concurrently to produce the light curve maxima. Light curves either side of the event show wave-like oscillations owing to the orbital period of AG Pegasi’s components, indicating quiescence.

2015年6月，共生双星AG Pegasi经历了一段爆发期。SkyCam T 安装在 2 m 的利物浦望远镜上，收集了该事件的 650 多张未经过滤的图像，以及之前和之后的数千张图像。本说明介绍了从这些图像中获得的 Sloan r ' 波段光曲线。此外，还包括使用 AAVSO 数据的色阶图 (CMD)，以推断系统白矮星 (WD) 的参数。光变曲线中的特征使人们可以将这种爆发归类为经典（或 Z 和）类型的爆发。CMD 表明 WD 的温度和光度同时增加以产生光变曲线最大值。由于 AG Pegasi 组件的轨道周期，事件两侧的光曲线显示出波状振荡，表明处于静止状态。
