3.3 Request further images

If you have time this week you can add additional data points to the light curve by requesting further images using the exposure time that you determined in Activity 2. When these return from COAST, process them in the same way. This will give you another observation of the variable star on a different date and time, which you can add to the light curve.

You may also want to check back from time to time to see if other participants have added any new points. As more data points are added, the light curve will continue to build up.
