我们报告了矮新星HS Vir（=PG 1341−079）的长期和时间分辨光度观测。1996年3月明亮爆发期间的时间分辨测光发现了周期为0.08059 ± 0.00003天的超级峰，首次确定HS Vir是SU UMa型矮新星的真正成员。HS Vir的爆发幅度很小（最亮的超爆发为2.7-3.5等），这是相当不寻常的。从与SX LMi的比较中推断出的显着多样性可能反映了这些矮新星中爆发幅度小的不同机制。
We report long‐term and time‐resolved photometric observations of the dwarf nova HS Vir (=PG 1341−079). Time‐resolved photometry during the bright outburst in 1996 March revealed superhumps with a period of 0.08059 ± 0.00003 days, which first firmly confirmed HS Vir as a genuine member of SU UMa–type dwarf novae. HS Vir is rather unusual in the smallness (2.7–3.5 mag for brightest superoutbursts) of outburst amplitudes. The marked diversity inferred from the comparison with SX LMi may reflect different mechanisms responsible for the smallness of outburst amplitudes in these dwarf novae.
