Welcome Jerry,

It is a lot quieter here these days than it used to be but there is a lot of useful information archived and I think quite a few people still drop in judging by the read statistics

My analysis of the spectrum at maximum. (ALPY600)

Not all type Ia are the same but SN 2025rbs looks like a very normal type Ia

A similar request for monitoring X Per had been received from Alexander Salganik University of Turku so it looks like there is some interest in this object again. See

I have received a request from Alexander Salganik University of Turku for long term spectroscopic monitoring of the X Ray Binary X Per which I am relaying to the various spectroscopy groups. It is similar monitoring to that requested by Paul Roche which covered mainly 2018-2021 and was reported on ...

I have used this excellent resource for many years to plan my observations of new transients and view the target field and details in SIMBAD. The author is a professional astronomer and responsive to suggestions of additions/improvements.

A paper including observations during this continuing campaign has been published today
"The birth of Be star disks I. From localized ejection to circularization"

And yet another prediction ATel using my high resolution H alpha spectrum from the ARAS database. (I have no connection with the authors)

"T CrB on the Verge of an Outburst"
I think they should have at least added a question mark ;-)

Double left click either end of the region of interest

Hi Paul,

I don't know the cause but It seems to me that it is not a stitching problem but a problem with the individual orders which show flip ups at the edges. The stitching is trying its best to fit to include those edge effects. A problem with the blaze profile in those regions ?
