----- Attempting Submission 2 (Wed Jan 04 20:11:46 GMT 2017) -----My dither shifts are really mini-mosaic shifts so I understand the aperture warnings.Supernova 1987A after 30 yearsThe 30th anniversary of the 1987A supernova is in early 2017. We propose a capstone observation of SN1987A using WFC3.We will perform deep WFC3/UVIS imaging with just the F657N filter (H-alpha plus NII), as much to detect the surrounding Tarantula Nebula as SN1987A itself. The dither pattern is essentially a stretched gap dither. The two main pointings cover each others chip gaps, but also stretch the field of view by almost 50 percent while still on one guide star acquisition. The large dither shift of 78 arcseconds can be reduced a bit to find suitable guide stars, if necessary, or the exposure times could be reduced by equal amounts.Stellar Physics3SUPPORTEDEXT-STARSUPERNOVAYESThis object was generated by the targetselector and retrieved from the SIMBAD database.J2000J2000WFC3/UVISImagingNoNoF657N/private/var/folders/tj/27ygn_756lz3w1z19s6wtgtm0006vh/T/OPVisit2398706839684445931.xmlThe scheduling data was generated by CASM 24.2.CASM was run in Phase II mode.(Tic-Visit
