General Description

EMMI longslit observations of PKS 2155-304 using Grism #1 on RILD.

Short longslit observation of the Halpha emission from this z=0.117 BL Lac.

3 x 60 second longslit observation of this (very bright) galaxy will be taken, with
 the object being nodded along the slit for each of the individual observations.

Standard calibration is required.

This is a ToO programme which we will execute a total of 5 times between July and
 September 2005. The time of execution depends upon the active state of PKS 2155-304

Critical Observing Condition Constraints

There are no critical observing conditions

Time-Critical Aspects

While these observations are part of a multiwavelength campaign, at the
 moment, executing the OB on the night of the trigger is sufficient.

ToO Information

This programme consists of 5 ToO OBs, with PKS 2155-304 as the target.
 Each OB consists of 3 short longslit exposures and the relevant calibration and
 acquisition runs and a spectroscopic observation of a standard star for flux calibration.
