V1405 Cas, a bright nova in Cassiopia, which has been hovering just above 8th magnitude has suddenly brightened to about mag 5.6. My latest estimate is mag 5.6 using a Slooh Digial Image in green light. Tried using VPhot but it didn't seem to working giving a much lower mag estimate. Not sure why. Here's the AAVSO lightcurve for this remarkable nova.

V1405 Cas is indeed brightening.

Latest reported visual to AAVSO are 5.4magnitude

including mine this early morning.

One can only guess how far this will go.....

Best for clear sky

My visual estimate from last night (first clear night in last days) :

09.05.2021    23.00 UT           m = 5.35   vis

 

Nova is certainly fainter than 4 Cas, but certainly brighter than 2 and 6 Cas.

I estimated V1405 Cas at mag 5.3 on the 10th.

It's close to M52 in Cassiopeia.

 

There are a bunch of images in this thread that show the nova:

V1405 Cassiopeiae will be over 40 degrees in altitude from my location at 5:00 a.m. EDT on Wednesday morning.  It's located ½° south of the bright open cluster M52, which is in brackets in this screen capture from Stellarium.
