I would like to request nightly photometry of T CrB to support my year-long Open University degree project, while I am away from my Observatory in Topsfield, MA. I am hoping to find small variations (different in each band) to see how the variability changes with respect to the phase of its orbital cycle.

Images: 3 images each night in each filter for the duration. I plan to stack the three images.
Filters: B, V and I (only).
Duration: about 28 March 2014 to about 28 April 2014.

Thank you,
John O'Neill (ONJ)
