General Description

• This program is aimed to determine the nova rate in two elliptical galaxies:
   NGC4621 and NGC 4374.
  Our goal is to monitor each galaxy with 4 different epochs/runs roughly 15 days
   apart from each other.
  Each run consist of imaging in the three filters B, V, and R. Occulting bars have
   been positioned to avoid heavy saturation from bright stars, thus the acquisition
   is in fims mode. 
  The exposure time saturates the very center of the galaxy nucleus but this is know
   and
  does not represent a major problem to our program.

Waiver Requests

• We requested to extend our OBs to 1h15min.
  The request 075.D-0491A.01 was approved. We received confirmation by Martino Romaniello
   on Feb18.

Critical Observing Condition Constraints

• We are looking for faint variable sources, therefore we ask for "grey"
   time, airmass 1.5 and 1" seeing.

Time-Critical Aspects

• A tipical timescale of the nova phenomenon is fifteen days therefore we
   need observations to be carried out every 15 -7/+10 days.
  
  This program is time critical in the sense that sticking as much as possible to
   the specified interval of 15 days between each epoch/run and the next would make
   considerably easier the nova identification.

Special Execution Requirements

• Comtemporary observations of our two targets are welcome but not necessary.
  
  For our science it is important to keep, as much as possible, the separation of
   15 days between consecutive observations of the same galaxy.
