Here's a rough spectrum I took of this comet this morning. It is showing dominance of continuum (sunlight reflection off dust) with little or no sign of gaseous C2 emissions, i.e. a VERY dusty comet. It also has a sodium emission (marked) which should increase in strength as the comet approaches perihelion. I couldn't graph it as my software (RSpec) won't open on my new laptop. Have to sort that out!
The comet is still a reasonably difficult get in morning skies and with a bright Moon. But it's coming along nicely!
