Re: Starlink V2 Mini BLUE color

The blue passes that I have been able to observe in this season of many
cloudy nights have approximately +50-90° of elevation, in the low altitude
passes below 30° I have not seen color.

I was also able to observe the train in the days after launch at altitudes
of 40°(I think, trying to remember) and I didn't see any color.

The blue color is observable with the naked eye from dark skies, although I
highly recommend its observation with binoculars, it is a very different
view from the color we are used to, observing other objects and having a
"mini starlink" crossing the field of vision captures all the attention for
its color.
