摘要：

We present images of the Galactic Center at J, H, K, and L with an effective FWHM of 0.4". No object is detected at the position of Sgr A* at any wavelength. The images generally confirm recent lunar occultation results. IRS 16 consists of five point sources and one extended source. The five point sources have colors consistent with reddened stars: two may be late-type field giants. The extended source is the reddest object in IRS 16 and shows a definite color gradient along a ridge from southwest to northeast.
