NSV 10934: refined superhump period Dear Colleagues, After incorporating the newly reported data, we obtained a mean superhump period of 0.074782(5) d. This value should be regarded as a long-term average, since the superhump period has been showing a decreasing trend. The average superhump profile is posted at: http://vsnet.kusastro.kyoto-u.ac.jp/pub/vsnet/DNe/NSV10934/10934sh.gif or on http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/nsv10934.html The extremely high accuracy of the observations is remarkable!
