And more structure. A bit noisier, though, especially at the red end. Whether down to terrible seeing (it was awful), moon , or what else I'm not quite sure.

The next few days are not going to be favourable for observing, so perhaps more over the weekend.

Further development - bit by bit. There was some high cloud around this evening, so a little more noise in spite of a longer exposure. Also there was a full moon at around the same azimuth as the target. So from here it can only get better.

Structure starting to emerge.

Not much in the way of structure emerging tonight.

Thanks Robin. On Sunday I initially thought I might have pointed at the wrong object, but eventually decided it was about right for an early Type II. The forecast for the coming week here is pretty good, so will hopefully capture some structure as it emerges. I've just kicked off another exposure a ...

Well, the weather has been a little more cooperative in New Zealand. I got a spectrum on Sunday (though a little compromised by high cloud), and one on Tuesday night. GELATO classifies them as unreliable Type II, which is probably about as good as I can hope for. sn2024ggi_ 20240414_325_Tom Love.png...

Surprisingly, I have had good weather tonight. So here is my fresh Alpy spectrum as well.

Thanks Olivier. My weather forecast is terrible for the next week, so I think it's over to you for now!

And an updated observation. This is a long (3 hour) exposure which shows a little more detail, though it's a bit noisy as we approach the near infrared.

This possibly explains why I have so often had difficulty getting accurate calibration with the Alpy, whereas I've never really had much of a problem with the Lhires. I have also often found the smile correction very volatile, sometimes getting quite different values with different lines selected fr...
