[vsnet-alert 9551] HS2331+3905: revised early superhump period

[Hiroyuki Maehara]

Dear colleagues,

We have received further time-series data from Michael Richmond 
(RIT Observatory) and KANATA team (R. Matsui, M. Uemura, A. Arai, 
M. Sasada, O. Nagae, Hiroshima University).

PDM period analysis to the combined data (from JD2454348.999 to 2454349.657)
yielded the best early superhump period of 0.05638 +/- 0.00003
days (81.19 min) which is nearly equal to the orbital period.

Further time-resolved observations are strongly encouraged.

Please report your time-series photometry of HS2331+3905 to:
vsnet-campaign-report at ooruri.kusastro.kyoto-u.ac.jp

Best regards,
