Epoch 2 observations for the MACSJ0416.1-2403 cluster and its parallel field have been scheduled and began executing yesterday. This epoch places WFC3/IR on the main cluster and ACS/WFC on the parallel field.
These observations will continue through late August and probably early September. You can watch the progress of the scheduling and execution of these observations on our status page:
The large exposure numbers listed in late August (at the time of this writing) merely indicate the total number of exposures during that observing window and that those exposures have not been planned on specific days yet.
Keep checking back and watch the observations add up!
