Tracing the mass-loss history from type II supernova explosions back through the red supergaint phase. We are requesting 21 orbits of HST WFC3 UV photometry to observe 10 non-interacting hydrogen rich Supernovae ( SNe II) from 50 to 300 days after explosion. This endeavor aims to yield invaluable insights into the mass loss history preceding the explosion, a phase of stellar evolution notoriously challenging to model. Recent observations of type II supernovae have revealed indications of significant circumstellar medium (CSM) interaction, suggesting red supergiant (RSG) progenitor stars experienced mass loss rates ranging from 10^-3 to 10^-1 solar masses in their final years before explosion, significantly higher than the 10^-6 solar masses per year typically observed in RSGs. To reconcile these findings, it is imperative to investigate mass loss from the progenitor star decades prior to the explosion, a task that requires observations within the 50-300 day timeframe post-explosion. Ultraviolet (UV) observations are the best way to trace CSM interaction via strong MgII emission, as predicted by models. This model's validity has been underscored by recent observations of SN2023ixf in M101 (~6.4 Mpc). Consequently, this non-disruptive Target of Opportunity (ToO) initiative aims to observe 10 SNe II post-explosion, to extend this investigation beyond a single object to encompass a larger sample of SNe II, thereby broadening our understanding of mass loss in red supergiants through the CSM interaction in typical type II supernovae. Given the limited lifespan of HST, this is the time to advance our knoledge on mass loss in RSG. We will observe 10 SNe II in between 50 and 300 days after explosion with WFC3+F275W and WFC3+F390W. We will request 2 epochs for each to trace the mass loss rate in the last ~ 10-100 years before explosion. Any SN II within 100 Mpc (at phase 50-300 days after explosion) will have magnitudes in the range 22-26 in WFC3+F275W and WFC3+F390W filters. We will observe each SN selected at two epochs: the first epoch will be around 50 days after explosion when the models predict that the Mg ii will start to be visible. The second epoch will be between 100 and 300 days after explosion, since after that the SN may become too faint to be detected. We will use 3 setups depending on the SN magnitude. Most SN will be in the range 21-22 for the first epoch (50-100 days after explosion) and 23-25 for the second epoch (100-300 days after explosion): - magnitude range 21-22: We will use a dither pattern with 2 pointings per filter. We will use a 2k x 2k sub-array allowing all 4 short exposures to be stored without losing time for buffer dump. We will request 2 extra exposures with the filter WFC3+F225W - magnitude range 23-25: We will use a dither pattern with 2 pointings per filter for a total of 4 exposures per orbit. Each exposure will be larger than 348 seconds to avoid losing time for the buffer dump. This strategy will give a S/N of at least 12-15 for the faintest objects. Each visit will be within one orbit and includes both filters. This setup will be use only for ~ 10 triggers. - magnitude range 25-26: We will use a dither pattern with 4 pointings per filter for a total of 4 exposures per orbit. Each exposure will be larger than 348 seconds to avoid losing time for the buffer dump. We will need one orbit per filter. This setup will be use only for one trigger. S.
