The spectrum is quite different from other comets I have measured, with an apparent absence of CN, C2(swan) and instead a series of bands in the red which I need to check but I suspect are NH2. See attached comparison with 2020 F3 Is this known to be a carbon depleted comet or is it something to do with the fragmentation perhaps ? Are there any pre fragmentation colour images which might show a presence or lack of blue/green emission ?
Cheers
