potentially bright supernova in NGC3254
A supernova has been reported in NGC3254
It is currently too faint for most amateurs at mag 18 (right at my limit) but according to the published spectrum it is a type Ia, possibly caught a remarkable 2 weeks before maximum so based on the distance to NGC3254 and that from the spectrum there does not seem to be much redenning, it could reach ~mag 13.   
One to watch!

SN 2019np

K Itagaki's latest image on David Bishop's site puts the SN brightness at around 13.6 (clear filter, presumably V mag zeropoint).

Unfortunately there's been quite poor weather in NE England recently - with just snatches of clear sky - so I haven't been able to get at this object.

Too early 8-(

It's happened 4 weeks too early for me.  Not back in La Palma until mid-February, where I can reach mag 20 or better with around an hour's exposure.  Can't even reach mag 8 from here.

Oh well.
