Estimated Total Execution Time (hours, including overheads)

• 03:00

General Description

• This is a simple LSS programme that attempts the recovery of the young
   SN remnant of SN1998bw.
  The SN is not visible anymore and, if any, the signature of the SN remnant should
   appear in the form of broad emission lines, possible very faint, and hence not directly
   visible in the single CR splitted spectra.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Constraints are not stringent, but observtion should be executed in grey
   time, at an airmass lower than 1.3 and with a seeing of 1".0 or better.

Time-Critical Aspects

• OBs shoudl be executed before mid August, so that observations at low
   airmass are possible
  for several hours.

Special Execution Requirements

• The only critical aspect of this program is the need for an accurate slit
   centering.
  The target is NOT expected to be visible in the acquisition and through slit images.
   For this reason we have used a blind offset from a reference star (R~17.8). In order
   to allow for an easier check of the slit alignment, we rotate the instrument such
   that both the reference star and the SN position will fall onto the slit. The angle
   has been calculated using FORS1 images taken at an epoch when the SN was still visible
   and, therefore, both the position angle and the offsets should be accurate.
  
  We have provided three finding charts:
  
  1) full FORS1 field of view;
  2) zoom on the SN region. In this f. chart the SN is still visible. The reference
   star
     is marked with a circle;
  3) zoom on the SN region. Similar to the previous, but the SN has disappeared.
