[vsnet-campaign-xray 15] V4641 Sgr and XTE J1118+480 last night obs.

[Makoto Uemura <uemura@kusastro.kyoto-u.ac.jp>]

Dear colleagues,

  From last night observation at Kyoto (vsnet-campaign-xray 13), 
we see V4641 Sgr at 13.39mag (unfiltered CCD photometry, near Rc). 
With the same equipment, we observed it last year, and obtain 
the average magnitude of 13.53mag.  These indicates that the 
object is in a little brighter state but in quiescence.

  As noticed by T. Kato in [vsnet-campaign-xray 14], the more rapid 
decline trend of XTE J1118+480 is more apparent.  Within this two weeks, 
the object has become about 0.3mag fainter.  The light curve observed 
last night is covered about three hours under good condition, but no 
prominent humps are detected.  The object may change its physical state 
during this rapid decline phase.  More observations are urged.

Regards,
Makoto Uemura
