[] V5588 Sgr : maximum light

f:id:kanataobslog:20110402002537p:image

We update the light curves of V5588 Sgr (=Nova Sgr 2011 No.2) in optical and near-infrared wavelength. The V, J and H band light curves show the slight decline, while the Ks-band light curve do not show the significant variation since previous day. This behavior may be a signature of dust formation as seen in V1280 Sco. We will continue the observations.
