 - **Phase**             :       3  
 - **Status**            :       Draft    
-- **Category**  :       Nighttime testing (functionality and operability) (C5)
-- **Recurrence**        :       once at commissioning
-- **Duration**  :       4 hours
+- **Category**  :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
+- **Recurrence**        :       once at commissioning and then on request.
+- **Duration**  :       2 hours
 
 **Description**
-- Verify the acquisition sequence for SHARK-NIR
+- Acquire a series of sky backgrounds from science images. A short sky background may also be useful for remaining deviant pixel removal. 
 
 **Prerequisites**
-- Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?).
 - Authorize SHARK-NIR on the SX side.
-- Suitable bright enough target (including the possibility of performing AO).
+- Atmospheric conditions: AO working conditions???
 
 **Procedure**
-- 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. 
-- Save telemetry (open and closed loop of the ALPAO DM).
+- Observe a blank field close to the science target (separation~10-20 arcsec) 
+- 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. 
 
 **Templates**
-- SHARKNIR_ci_acq (not released) - coronagraphic mode
-- SHARKNIR_di_acq (not released) - direct imaging mode
-- SHARKNIR_lss_acq (not released) - long slit spectroscopy mode
+- SHARKNIR_cal_SkyBackground (not released)
 
 **Success criteria**
-- Successful acquisition sequence.
+- 10% accuracy (dependent on measurement frequency) 
 
 **Notes**
+- Same as activity 7.6 in AD4
 
 **LBTO support**
-- AO support
 
 **Date performed and by whom**
