It's very cold these days in Hong Kong (of course, using Hong Kong's standard), cold wind blowing and that's the reason why the temperature keeps dropping. It translates to poor seeing. The dusty sky is cleared as a side effect.
Seeing 2/10, transparency 8/10.
I pulled out my Widescan 20mm to have a look, very interesting but not as active as the last time. Prominences here and there, but yet small. That filament is very nice and dark.
