View here: Details for CS Ind HST schedule set for August 30
Abstract: Further to AAVSO Alert Notice 838 (Alert Notice 838: Monitoring requested for 11 dwarf novae in support of HST observations in 2023-2024 (backup copy) | aavso), Dr. Anna Francesca Pala (European Space Agency, ESAC, Spain) informs us that the cataclysmic variable CS Ind is scheduled to be observed with the Hubble Space Telescope on: 2024 August 30 00:37:21 - 03:58:19 UT. Beginning immediately, please observe CS Ind in V nightly through August 26, then a few times per night through August 30, then nightly through September 13. As with all targets for HST, a positive V measurement 24 hours before the scheduled HST time will be crucial so the HST team can make a go-nogo decision; the nights of August 27-28, 28-29 will be critical. Finder charts with comparison stars may be created using the AAVSO Variable Star Plotter (Variable Star Plotter). Submit observations to the AAVSO via WebObs using the name CS IND.
Justification: CS Ind is one of the targets being covered in this, the third year of this campaign on cataclysmic variables. Optical coverage in V is essential to confirm that the target is not in outburst and so may safely be observed by HST. Without this confirmation, HST observations will not proceed. Optical coverage also allows for the HST observations to be analyzed in context of the optical behavior of the target. Coverage by AAVSO observers is therefore critical to this campaign.
