Hi Patrick,

Thank you very much for this information.
So there is no transient at least with mag around 16 at the place of the coordinates of 18lx.
I will remove the star from my observing list.

Regards,

Josch

Hi Josch,
 
I would say ASASSN-18lx is invisble in the 'small crop' that you provided.

Quote from https://www.aavso.org/vsx/index.php?view=detail.top&oid=621378:

The transient should be located between the 14.9 and 15.1 mag. stars.

This is the 14.9 mag. star 7" to the SSE.

Clear skies,
Patrick

Observations of ASASSN-18lx and correct identification of the star

Hi,

I have started observations of ASASSN-18lx.

With the given coordinates from the ASASSN transient page and the one from the AAVSO sequence, the position is between two stars.

I have chosen the star indicated in the small crop in attachment which seem to be one indicated on the AAVSO chart for 18lx.
However the coordinates of this star have end ciphers:
RA 58.11, DEC 23.8

Is anybody else observing this star and has some advice to which coordinates are correct? Any help is appreciated.

Regards,
Grüße,
Groeten,
