I made a second observation of the nova in Lupus last night (Sep 27). It had faded from a visual magnitude of 6.7 on Monday to 7.2 (both in purple below). Observations since then show a further brightness decline.
I was pleased to see my first observation counted among those submitted by Elizabeth Waagen (AAVSO) for inclusion in “telegram 4322” from the the Central Bureau for Astronomical Telegrams in Harvard (my first). See the AAVSO alert from Elizabeth for more details.
There was no chance of another observation tonight after the storm here in Adelaide today; no power so no light pollution but no clear sky either. I’d say another day or two will go by before I can observe it again.
