    Hi,
    I have been observing the SN when i can since 5th. I am recording magnitudes after basic calibration and reduction and using aperture photometry.
    So these are “instrumental” magnitudes and i am acutely aware I did not use my photometry filters. So are blunt readings.
    I’m recording when i can through the cloud simply to derive a consistently produced light curve for educational use.
    That said, these are the measurements so far.
    All integrated at approx 22.00UTC from South East UK

    5th Sept – m13.7
    8th Sept – m12.9
    10th Sept – m12.7

    So yes, getting brighter, but by my reckoning it might be levelling off. Which is what we might expect with a T1a.
    The next few nights will be interesting.

    I have been uploaded images of each observation in the britastro gallery.

    HI Ken
    Do you have a version with references? As it’s a bit difficult to track your notes without any citations and/or sources?
    Regards

    Thanks for the reply
    No, Astroart isnt doing anything clever. Its just spreading the RGB simulated channels across the visible image histogram. So using the histogram if i tweak the blue channel down then the central disk (becomes more defined as is overexposed in unstretched image) and likewise those prominences are all in the red channel (as transferred across from the mono image)
    Its a 16bit image so loads of scope to tweak.

    Im doing a BSc in Astronomy and have literally just started a heavy Solarastrophysics module. Trying to put it all into context with what can be seen.

    The visible radiation from particle does technically display doppler effects (due to speeds of the material outflow) but yeah… .logically the mono chip (a Player One Neptune-M camera) sampling must be catching the whole passband if i think about it.

    I have indeed tried tweaking the pressure passband adjustment and yes, have some images at different values. I shall have a play and see where it leads me!

    Thanks again for coming back to me

    Thanks folks for all those helpful replies.

    Well I was glad I raised to question as now know where to look for verification etc…

    Will keep looking though!
