The latest Astronomer’s Telegram, ATel #17960 details more spectroscopic observations. A bit better than mine….but they do have a 2.0 meter telescope on La Palma…!
The narrow spectral lines don’t show well at the much lower resolution of my spectrum. But the atmospheric absorption (Telluric) bands are clearer…I’m looking through a lot more atmosphere than they are…(!)
