I'm new at this. Please advise if I missed anything!

The TAC suggests adding B and Ic filters to the observing list.

Sounds like a good idea. How do I do this?
If we add those, I think the imaging sequence would be: Ic, R, V, B, B, V, R, Ic, Ic, R, V, B

Plan committed to both NH and NM. Runs every two clear nights. Used BVI filters x3. Check exposure when you get email about images in your VPhot account.
