V4641 Sgr: optical observation

We obseved V4641 Sgr tonight (16 Oct.).

YYYMMDD(UT)     V           V_err    Observatory
20081016.390     13.45     0.01      Higashi-Hiroshima Observatory

We found it is still acrive; ~0.1 - 0.15 mag brighter  than at its 
quiescent level.

We also took a low-resolution spectrum tonight,
which show no prominent emission line.

Follow-up observations are urged.
