General Description

General description 277.D5032(B):
ISAAC IMAGING of RSN in SBS0335-052
-----------------------------------

We want to first acquire broadband imaging in VRI (FORS2) +J (ISAAC)
of a radio supernova (RSN) in SBS0335-052. Please see the README of 
277.D5032(A) for the FORS2 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)].

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.
