As I understand it from Paul Roche’s comments this is a long term project (with a timescale of years), primarily to alert when there has been a change in the disc state, indicated by changes in the H alpha line so similar to typical Be star monitoring. Though this would likely change if something significant is seen. High resolution H alpha spectra will probably show more subtle changes first but a low resolution spectrum would also pick up significant changes in emission line strength so I would suggest an occasional look say once every few weeks or so, particularly if you see in the BAA database (where most of the campaign spectra are being stored) that there has been a significant gap since the last observation.
