0 Assigned ID: 10 ----- Attempting Submission 1 (Sun Jun 24 21:54:24 GMT 2018) ----- I relaxed the ORIENT range such that we can get ORIENT=123 which is only 10 degrees off our desired 133 deg (to match existing archival data). To compensate for the small rotation, I also nudged the target coordinates a bit. Please schedule this non-disruptively but as soon as possible. -- Max Mutchler -1461616225 ----- Attempting Submission 1 (Fri Jun 29 18:43:35 GMT 2018) ----- ----- Attempting Submission 2 (Wed Aug 08 20:07:43 GMT 2018) ----- I have confirmed the pointing matches the existing WFC3 image in Aladin, to within 10 degrees. Infrared imaging of stellar shading in Serpens Nebula EC 82 We propose infrared imaging of the Serpens Nebula EC 82 to reveal shading by a circumstellar stellar disk around a young stellar object. We expect our observations to reveal new features and add color information to existing archival infrared images. We will also obtain deep narrowband imaging of another part of this molecular cloud with parallel ACS exposures. We will use a single WFC3/IR pointing matched very closely to the existing H-band (F160W) image from HST program 14181 (PI Thomas Megeath) which is at ORIENT=133 degrees. This ideal orientation is available from late July to mid-August 2018, and other acceptable orientations at 90-degree increments are available later. We will obtain J-band and narrowband [Fe II] images using filters F125W and F164N, respectively, to be combined with the existing H-band image. We will also obtain deep H-alpha plus [N II] images of an adjacent part of the molecular cloud using the ACS in parallel with the F658N filter.
