Comet C/2025 A6 (Lemmon) is doing very well already, months before its perihelion - and it's not a transient outburst: "To measure the total brightness, the entire coma of 7' was used in Astrometrica," writes Michael Jäger in https://www.facebook.com/groups/227002358661288/posts/1549648323063345 where he finds "m1-10m6, the comet became about 1 magnitude brighter between August 19 and 27. This is not an outburst." This #comet could thus reach 2nd or 1st magnitude in late October / early November when it's observable in Ser, Her and Oph at a solar elongation of around 35° ... unless it decides to stay dimmer, of course.
