Abstract:
    We present a multi-epoch infrared photometric study of the
    intermediate-mass star-forming region G173.58+2.45. Photometric
    observations are obtained using the near-infrared JHKL'M' filters and
    narrow-band filters centred at the wavelengths of the
    H2(1-0)S(1)(2.122um) and [FeII](1.644um) lines. The H2 image shows
    molecular emission from shocked gas, implying the presence of multiple
    star formation and associated outflow activity. We see evidence for
    several collimated outflows.

Description:
    Observations were acquired with the 3.8-m United Kingdom Infrared
    Telescope (UKIRT), Mauna Kea, Hawaii. Photometry in the J and K bands
    was obtained on 2001 December 26 using UFTI equipped with a Rockwell
    1024x1024 HgCdTe array. The region was observed again using UFTI on
    2002 October 22 in the H and K bands and in narrow-band filters at the
    wavelengths of the H2 v=1-0S(1) line (2.1218um) and the
    [FeII]a4D7/2-a4F9/2 line (1.6439um), and on 2002 November 6,
    in the J band.
