General Description

• General description 277.D5032(A):
  FORS2 IMAGING of RSN in SBS0335-052
  -----------------------------------
  
  We want to first acquire broadband imaging in VRI (FORS2) +JKs (ISAAC)
  of a radio supernova (RSN) in SBS0335-052. Please see the README of 
  277.D5032(B) for the ISAAC considerations.
  
  The general FOV is indicated in the finding chart "sbs0335_hst_chart.jpg"; the
  image is HST/WFPC2 (F790W).  The source is marked in that chart with a red
  arrow, but is shown in an enlarged finding chart with astrometric coordinates
  in "rsn_7mm_hst.jpg".  This last shows the 7mm VLA detection overlaid on the
  same HST/F790W image as the other chart.
  
  Coordinates (J2000) provided for imaging are those of the brightest southern 
  superstar clusters (SSCs); the RSN will have slightly different coordinates
  (RA = 03:37:44.060 DEC = -05:02:38.6) which will have to be refined for
  spectroscopy [see 277.D-5032(C,D)].
  
  FORS2 IMAGING--
  I've divided the V and R exposures into two positions/offsets, and the I-band
  exposures into four positions/offsets; please check that this strategy is
  correct for good elimination of bad pixels and cosmic rays, and that these
  on-chip exposure times are sufficiently long to be in the background-limited
  performance regime.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• We request seeing around or better than 0.8arcsec. Better seeing would
   be
  (obviously) even better. The transient source lies within several star clusters
  in a dwarf galaxy, separated by only 1 arcsec or so. Hence, good seeing is
  necessary to best separate the new sources from the surrounding clusters.
  
  Photometric conditions are necessary because of the need to assess the
  viability of spectroscopic followup.

Time-Critical Aspects

• We need the imaging observations to be relatively close in time because
   of the
  transient and variable nature of the source (radio supernova). But "close" is
  relative; the observations should be as contiguous as possible given the
  instrumental and logistical constraints.
