[vsnet-alert 97] U Gem ephemeris

[Daisaku Nogami <nogami@kusastro.kyoto-u.ac.jp>]

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
