The sky was clear again evening. Seeing was good but transparency was very poor. It started with 3/5 but deteriorated to 2/5. I could hardly see Antares!
The SEB outbreak is still going strong. Note the bright white spot at it's center! The STrD-2 has really faded but is still visible!
The GRS is setting at this image. The NEB is very busy with a lot of rift activity. The NTB at this region is still pale.

Seeing typical for 17 deg. alt.
I tried the 807nm filter,going down to 5fps to compensate for the low signal
at that wavelength,at the end of the sequence,with some success. (Focal length
is slightly greater for that image for instrumental reasons). The colour image
uses a R-IR image taken 3 mins before the R as its luminance.
The activity of the SEB revival is central in these images,but not
well-resolved. STrD II is visible faintly as a bridge across the STrZ,almost on
the CM by the last image,sweeping into the narrow STB like smoke deflected by a
wind. The "angled belt" effect produced by the SEB activity is also prominent.
Neither of these features really appear like this in high-res images from the
same period,but these distortions caused by limited resolution are instructive.
