[vsnet-campaign-xray 8] XTE J1118+480 new light curves

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

Dear colleagues,

  New light curves of XTE J1118+480 additionally including the data 
on JD 2451730 - 2451740, can be seen at:

http://www.kusastro.kyoto-u.ac.jp/vsnet/Xray/xtej1118-camp.html

During JD 2451730 - 2451740, the light curve shows possible multiple 
peaks within one period calculated to be 0.1696(2)d.
The shape of the hump looks like changed from those of JD 2451710 - 2451730. 
The number of observations is 1146, which is larger than the last ten days.

It keeps general decline, but the decline speed became more rapid.
The mean decline rate is calculated to be 0.015 mag/d, faster than 
the previous speed during JD 2451660 - 2451730 of 0.006 mag/d.
This change seems to be not smooth but sharp around JD 2451730.

This object is still bright and humps are still prominent.
The activity has been observed during this fading phase. 
Even an hour- or a half of an hour- observations at some observatory of
different longitude will be very useful to study them.

Makoto Uemura
