     5- **Category**  :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)

    79**Description**
    8 •       Verify the acquisition sequence for SHARK-NIR
     10- Acquire a series of sky backgrounds from science images. A short sky background may also be useful for remaining deviant pixel removal.
     11
    912**Prerequisites**
    10 •       Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?).
    11 •       Authorize SHARK-NIR on the SX side.
    12 •       Suitable bright enough target (including the possibility of performing AO).
     13- Authorize SHARK-NIR on the SX side.
     14- Atmospheric conditions: AO working conditions???
     15
    1316**Procedure**
    14 •       Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM.
    15 •       Save telemetry (open and closed loop of the ALPAO DM).
     17- Observe a blank field close to the science target (separation~10-20 arcsec)
     18- The same set-up as nighttime science observations, but AO is not running, and the coronagraph may be removed. A list of telescope offsets is added to reach an “empty” field and jitter.

    1622**Success criteria**
    17 •       Successful acquisition sequence.
     23- 10% accuracy (dependent on measurement frequency)

    1825**Notes**
     26- Same as activity 7.6 in AD4
