Transient supersoft X-ray sources: monitoring the evolution

We propose monitoring observations of supersoft Xray sources. The classicalnova V4743 Sgr, for which the best spectra of a luminous supersoft Xray sourcehave ever been obtained, should be monitored once again during the coming year,also in order to measure the length of hydrogen burning. We then propose that RXJ0533.77034, a transient source observed for a few months in the LMC and neverfound to be luminous again, should be observed in five short snapshot exposures(every two and a half months) so that we may determine whether it underwent ahydrogen shell flash, and what its recurrence time scale may be. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
