     Along with SDSS-DSS-Vizier, folks should add Pan-STARRS
to the surveys to be checked for these transients.  In the south
the new SkyMapper survey should also be searched.
     Pan-STARRS is in VizieR (item II/349), so should come up
in a generic search.  This provides multiple epochs of
observation, versus only n=1 usually for SDSS.
     SkyMapper is not yet at VizieR, but has a query page here:

http://skymapper.anu.edu.au/cone-search/

This covers the entire southern sky between about mag 9 and 18
in Sloan g,r,i,z plus two very useful filters in the violet.
