Last week I tried to see the comet before dawn above the northeast horizon, and each time I tried there were just enough low clouds to obscure it. Hopefully I’ll have better luck in the dusk sky this coming week.
That’s the deal with low horizon stuff. When we look towards the horizon, it’s looking through the thickest part of the atmosphere, where there is denser air, dust, fog, clouds, more land obstructions etc. It’s why astronomers who take images of deep space objects, it’s always better for them if possible to chose targets near zenith, or close to straight up, where the air or atmosphere is much thinner.
Good luck.
