Test exposures requested for symbiotic binary candidates
Abstract:
We request observations to determine the current V, B, and U band magnitudes of the following candidate symbiotic stars, to help with planning for future observations. A single observation in each available filter would be sufficient; we are not requesting monitoring at this time, just approximate current magnitudes. Many of these targets have plenty of archival data, but we cannot assume that they have varied in predictable ways, so we require new test exposures.
Justification:
Determine the current V, B, and U band magnitudes of candidate symbiotic stars for planning future observations.
