 Today's 20210713 (yyyymmdd) pass around 22:10 (20:10 UTC) from Granada
I did not take a photo because the sky was still very clear. Tianhe-I
passed north of Vega, but also had Arcturus in sight. Tianhe-I began to
continuously brighten her from the zenith of her pass (maybe +0.5), towards
the East.  Although the sky was still very clear, as it passed through Vega
its magnitude was at least around -1.0 and so it continued until it was
lost, not much further between the rooftops.  In Heavens-Above they gave it
a maximum magnitude of +1.7, with the clarity it had, it would have been
very difficult to see but it seems that its brightness increases when it is
opposed to the Sun
