The object recently announced as ASASSN-17ib had already been published two days ago as ASASSN-17hx.
There is a 19.1 Gaia magnitude star at that position so the outburst has an amplitude of only 7 mag. up to now. Let's see how it evolves.
Is there anywhere the complete photometry for reference stars in the field of Nova Sct 2017? I only have the V-band value and I like to have B, I, Sloan gri...
According to Arne the best and easiest source for Sloan values is for the user to query APASS 9, https://www.aavso.org/download-apass-data, and manually get the Sloan photometry for the sequence star in question.
I gave it a try and if you use a very small radius like 0.01 degrees, it will usually return just the star in question.
