The EROS2 microlensing search will end at the end of 2002. Apart of this
microlensing search, EROS has discovered ~70 supernovae during 8 periods
partially dedicated to a SN search. In this document, we investigated a new way
of using the EROS telescope (The MARLY) after this date, as a dedicated nearby
supernovae photometer. The performance of a set-up with two cameras allowing to
simultaneously perform BVRI and U photometry have been estimated. Each year, of
order of 100 type Ia supernovae at z ~0.05 should be photometrically
followed-up during 80 days with a precision of 2% in BVRI and ~3,5% in U.Comment: You can find the full resolution of this report at
