The AAVSO has requested observations of V5668 Sgr (Nova Sgr 2015 No. 2) in support of Hubble Space Telescope observations of the nova.
Observations are needed of brightness ahead of the Hubble observations to set the correct exposudre to quote the AAVSO.
"The STIS observation will be carried out on 2015 November 6 around 01 hour UT. Beginning immediately, observers are requested to observe V5668 Sgr in B, V, and SDSS g' bands. Because the spectra will be taken in the UV and far UV regions, the bluer the monitoring band, the better; B photometry will be particularly valuable. Visual observations are also welcome. Nightly observations are requested through November 13; time series observations are not necessary."
