While PS1 is working well in producing regular transient stream for the Medium Deep Survey fields, these are typically too faint for NTT+EFOSC2. Mean mag is r~22, with typically ~100 targets per year in the MDS fields brighter than r~21 at peak. Only 4 of these fields are accessible from the south, so the MDS fields are not a viable source of targets for PESSTO.

The 3Pi search is starting to make progress and transients and vast numbers of asteroids have been discovered. The data is certainly good enough for a wide-field, local Universe search (similar mag limits to PTF, LaSILLA/QUEST and SkyMapper), and it is a matter of getting the processing up to speed.
