There is a report of another possible nova in Scorpius at Central Bureau of Astronomical Telegraphs:

The presence of a transient seems well-established, and amplitude of eruption seems consistent with a nova - has anybody confirmed its nature spectroscopically yet?
Thanks - Koji
There is already a "Time Sensitive Alerts" thread: https://www.aavso.org/pnv-j17180658-3204279-possible-nova-110-mag-scorp…
