1996 年 4 月 SW UMa 超爆发的差分 CCD 光度测量在尼古拉斯·哥白尼天文台和京都大学大田站进行。尽管检测到了周期为0.05818(±0.00 002)d的超级峰和可能的小幅度准周期振荡(QPO)，但我们未能找到所谓的超级QPO。 SW UMa 已被证明是继 AL Com、V1028 Cyg 和 HV Vir 之后的第四颗 SU UMa 型矮新星，其中对超驼峰极大值时间的分析表明超驼峰周期有所增加。
Differential CCD photometry of the 1996 April superoutburst of SW UMa was performed both at the Nicholas Copernicus Observatory and at the Ouda Station, Kyoto University. Although superhumps with a period of 0.05818(±0.00 002) d and possible small-amplitude quasi periodic oscillations (QPOs) were de tected, we failed to find the so-called super-QPOs. SW UMa has been proved to be the fourth SU UMa-type dwarf nova, following AL Com, V1028 Cyg, and HV Vir, in which an analysis of the superhump maxima timings revealed an increase in the superhump period.
