P72-020: Physical properties of near-Sun asteroids via polarimetry

PI: Mikael Granvik

This is a SoftToO (1 hour) and Monitoring program (10.4 hours) using ALFOSC imaging polarimetry of objects with non-sidereal tracking.

The PI will indicate as a comment in the OBs the correct name to use for the target and the exact use of the command tcs.asteph.

Instrument setup:

FAPOL: lambda/2
ALFOSC: Calcite
ALFOSC: UBVRi.

Daytime calibrations:

Polarimetric domeflats. Evening twilight flats. Morning alfosc-calibs.

Monitoring Schedule

Date           UT-window     Duration

TBD

The OB generator will be used to request all observations.

For the observer:

Go to the directory
cd ~/scripts/72-020
List the available scripts
ls -lrt
and execute the OB generated scripts for the appropriate date as requested.

Please, update the SoftToO or Monitoring tracking log of this program.
