Proposal

I come through this proposal to request photometry multi-filter of two targets studied by the citizen science project HOYS (Hunting Outbursts in Young Stars) at the University of Kent, this project by researcher/professor Dr. Dirk Froebrich. The purpose of studying the targets is long-term monitoring of clusters containing young stars to study their structure and behavior.
The two stars are YSOs that have already shown declines in brightness equal to or greater than 1 magnitude. Which makes them interesting objects to follow and are on the GAIA alert list of stars monitored by the HOYS project.
I would like to request that the proposal verification team indicate exposure time based on the magnitudes reported below.
As mentioned earlier, the purpose of the proposal is to contribute to the citizen science project HOYS, the images will be sent to the HOYS database and used in studies that will be published in the future by Dr. Dirk. there will be science done with them. And also to report the data to the AAVSO.

You have not provided any info on what specific filters, or how frequently you want images. Are these targets usually faint or bright with outbursts or eclipses, respectively?

I added information regarding filters and frequency to the proposal:
The required photometry is BVRI. Images can be provided 4 times a week if possible.

The targets present rapid variations in brightness and may present sudden and non-periodic drops in brightness, such as those alerted by GAIA.
