Dear colleagues,
As you know, the information that Outburst of U Gem was finally caused was distributed via vsnet-alert. Moreover, it has already been announced by T. Kato via vsnet-alert that eclipses of U Gem are expected to reach primary minima at:
Min = 2437638.82627 + 0.1769061898*E (HJD)
(+/- 8) (+/- 30)
(J. Smak 1993, Acta Astronomica, 43, 121)
This formula tells a primary minimum occurs at 2449809.264503 in HJD (E = 68796). The observation of eclipses in this outburst is highly encouraged. We (Ouda Team) tried to observe eclipses of U Gem at Ouda Station tonight, but the weather did not permit. Are there any sites where the high-speed photometry can be made?
Best regards,
Daisaku Nogami
