Estimated Total Execution Time (hours, including overheads)

• Maximum 13.2 hrs - but this is a ToO project.

General Description

• The purpose of the project is to follow the spectropolarimetric observation
   of SNe, typically during the first 2-4 weeks after discovery.  For exceptionally
   bright and nearby SNe possibly also longer.
  
  
  The required accuracy is 0.1% in the degree of the polarization.
  
  All OBs come in 2 flavors:  with and without order-sorting filter.  In the activating
   message, we will inform Paranal which ones to use.

Waiver Requests

• Waiver 076.D-0178A.01.WAV was issued on July 12 (Marina Rejkuba).
  
  The total excution time of OBs may exceed the one-hour limit.

Critical Observing Condition Constraints

• Moonlight is highly polarized and so needs to be avoided.
  
  Variable thin cirrus are acceptable.
  
  The seeing should be about 1 arcsec.
  
  Depending on the apparent magnitude and special properties of a given SN, we may
   replace the constraint set with somewhat more relaxed values.

Time-Critical Aspects

• The observations do not need to be coordinated with other observatories.
  
  The first observation of each SN should be obtained as soon as possible.  Within
   1 or 2 days thereafter, we can inform Paranal whether more observations of the same
   SN are desirable.  Normally, this gives a lead time of 1-5 days for the next observation.
    Similar for any observations at still later epochs.

Special Execution Requirements

• None.

Special Calibration Information

• We understand that the calibration plan foresees observation of polarized
   and unpolarized standards.  Therefore, we do not request dedicated observations
   of this kind.
  
  However, we are asking to observe within 2-3 days of each SN observation a spectrophotometric
   standard.  Please note that it will be sufficient to observe this standard at just
   one PA of the Wollaston.
  
  We submit OBs for daytime calibrations.  But if our colleagues on Paranal judge
   the default daytime calibrations as superior, we will gladly benefit from them.

ToO Information

• This is a ToO project.  The targets are SNe in nearby galaxies.
