Proposal

This new outbursting object, presumably a nova, is coincident with a known W UMa binary. As such, there is an outside chance that this is a merging event, similar to V838 Mon or V1309 Sco. I would like to monitor its evolution, both with BVRI photometry as well as with the BSM_NH2 diffraction grating. Photometric observations will be reported daily (VPHOT transfer option requested). Daily observations are requested for now - I'm assuming other observers will do time series to look for periods.

What is focus offset for Grating GR?

Committed to NH2

I checked on NH2 this morning, and the field is too far north to pick up this early in the season. Can you assign me to BSM_TX for the next week or so as well? Thanks. GR defocus is +250 units.
