PI: Alicia López-Oramas (alicia.lopez@iac.es)

Source information

  Source: WR140 

    RA (J2000): 305.117 deg 

    Dec (J2000): 43.8544 deg 

Observational settings/limits

Min Zenith [deg] = 5 

Max Zenith [deg] = 60 

Night Sky Background = Dark 

Wobbles = Standard 

Scheduling

From the proposal:

  We will plan our observations according to the orbital configurations (observations will be coordinated with the schedulers) and possible external triggers.

The configurations expected are:

phase  Orbital phenomenon          MJD         Date
