V844 Her monitoring requested
Active Dates: July 11, 2023 – July 11, 2023
Abstract:
Dual-purpose campaign to monitor the SU UMa-type cataclysmic variable V844 Her, focusing on a 29-minute periodicity during outbursts to trigger X-ray observations from Swift and confirm the periodicity through time series CCD observations.
Justification:
V844 Her shows a 29 minute periodicity during outbursts that may be the rotation period of a magnetic white dwarf. Observations are needed to trigger X-ray observations early in the burst and confirm the periodicity.
