ToO Description

This page is no longer relevant.

 

A nearby supernova has been detected. We request that a Nod-and-Shuffle observation be taken with WiFeS tonight at your earliest convenience. A visibility chart is provided below to help with scheduling.

We will pay back your time lost observing this object on Chris Lidman's scheduled payback nights at the end of the quarter. This ToO is scheduled to take 1 hour (45 mins on the object, 15 mins of callibrations), however I understand complications may arise, so please keep track of time lost so I can pay you back in full.

If you have any questions, feel free to email Brad brad.tucker@anu.edu.au, Chris christopher.lidman@anu.edu.au, or Harrison harrison.abbot@anu.edu.au.

Finder Chart

For best finding chart, use the finding chart from the Transient Name Server.

In the case where no finding chart is available, we provide a DSS image as a backup. DSS image shows a 5x5arcmin section of sky centred at the RA and DEC listed above

Altitude Plot

Plotted below is the altitude of our supernova (and the moon) over the course of the night. Grey zones indicate twilight hours

Observing Instructions

 

  1.  Slew the telescope (can be done while an exposure is being read out, and guiding will be automatically stopped)
  2.  Select the acquisition aperture and click Select
  3.  Take image with AG
  4.  Click on the SN
  5.  Click Move to aperture
  6.  Click Calpoint on the TCS GUI if you had to make a large offset. Check that the collimation constants are less than 10"
  7.  Select the aperture that defines the center of the WiFes FoV (it is not the 0 aperture) and click Select
  8.  Select a guide star with cursor and click set guide ref. Use long (i.e. 20 sec integrations on the guider if you need to.
  9.  Define the beams. Only the object position requires guide star coordinates.
  10.  Select beam A
  11.  Clear the fields
  12.  Click on object
  13.  Click on a nearby guide star
  14.  Save
  15.  Select beam B
  16.  Clear the fields
  17.  Enter the sky position. It is currently
    RA:06 39 50.6997
    DEC:-32 49 29.7252
  18.  Click the guide box for beam A on the TAROS WFS GUI
  19.  Define the instrument setup. Nod-and-shuffle, sky exposure time = Object exposure time, Nod-and-shuffle cycles=4
  20.  Add the object name
  21.  Set the observation to OBJECT (if you miss this, then it does not nod-and-shuffle)
  22.  Start exposure

Callibration Frames

Can be done at beginning/end of night, or use pre-existing if observer already performed them with above frame settings.
NOTE: Avoid exposing immediately after taking arcs due to CCD oversaturation, take short dark frames until arc lines disappear, ~1min
