It's strange that nobody is started this subject here yet ?

This new strange object is quite easy to see, this morning I estimated a +12.3 magnitude, quite stable.

 

Some days ago I started the topic in the sketching forum, look here :

If you'r an earlybird try it!

After CTA102 and the last micro lense, it's just a small point like a faint star too, but this is really another exotic object.

A new secondary outburst is on the way:

March 17 - 4:00 UT I did a difficult visual estimation: mag +14 but the light curve is going up.

Clear sky!

I'm going to try to image this interesting tonight. It seems the AAVSO has been studying this object for at least a year.

I imaged ASASSN-18ey last night (3/20) and estimated its magnitude at 13.8 using comp stars 129 and 138.

I imaged ASASSN-18ey again last night (3/21) and it's starting to fade. I estimated its magnitude at 14.0 using comp stars 138 and 146.

Same impression that yours Rich, this morning I estimate the mag : 14.3 with the same stars than yours.  Anyway that was difficult with my small 250 Mewlon, only glimpsed.  Here my last "composition"

Clear sky to you all
