Tony, a few comments...

"If the azimuth of the flaring satellites and that of the Sun were approximately equal, then they are probably alike".

Although the brightest flares and more regularly occurring ones have been in the NW, they have not always flared in the "sweet spot" and they flared on lesser occasions back when the sun's azimuth was significantly less (i.e. winter)

"In any case, it is very interesting that Starlink flares now seem to be
almost common. I am not aware of any flares being reported before this
month. Perhaps other people know of them?"

I agree they are more common lately (although tonight was a bust), but there have been quite a few previously. The difference is that all of the recent bright flares have been brighter, and more like the MMA flares from Iridiums and a few others. The previous flares and the short ones like the one seen tonight are similar to panel flares or flashes.

One thing is for sure - the answer is going to require a lot more data. I am not an analyst, but I would think StarLink is still testing, which may change the mirror angles and they may not be lined out for a while. I certainly hope that they are working on DarkerSat.
