Were you just looking with the naked eye *Oldnproud? We just had a faint red haze across the sky, but when my son got his phone out it showed all the incredible colours. Such a thrill, I've waited 78 years to see it.
Yes, just with the naked eye. If i ever get the opportunity again, i will certainly use my phone. That said, I never saw any colour at all - not the slightest hint of red or green - so I don't think it would have made any difference.
Fingers crossed I get another opportunity in my lifetime.
