HST schedule set for ASSN-18dg
Abstract:
Dr. Anna Francesca Pala (European Space Agency, ESAC, Spain) informs us that observations of the cataclysmic variable ASASSN-18dg have been scheduled with the Hubble Space Telescope for 2024 January 11 UT. Observers are requested to observe ASASSN-18dg in V one to a few times per night from now through January 11, then nightly through January 27. A minimum SNR~20 is requested.
Justification:
The monitoring to assess quiescence should have the highest priority since, without it, there is the risk to lose the allocated orbits.
Requested Data Types:
