C/2023 A3, 16 months to Prepare

As a comparison the proposed peak magnitude puts this comet somewhere within that of the planets Saturn and Mars.
 
Now inside the orbit of Jupiter.
 
A couple of sites are predicting this might now get to mag -1.8 based on recent data, making it almost as bright as Mars at perihelion.
 
Not looking good, it might be early August before it's visible.
 
A better chance of 'before sunrise' observation from the 16th onwards (totally overcast here so no chance)
 
Update. A3 could be seen briefly before 7am if tomorrow morning is clear (mag 1)
