Analysts: if a sudden jump in delta T residuals is present compared to usual,
let me know: I used a different DCF clock this time as the one I used for years
died on me yesterday.

Clear sky. USA 186 was bright and briefly flared to mag 0 near ~19:25:25 UT (25
March). It was some 8.6 seconds late and 0.14 deg cross-track compared to a
3-day-old elset.

I imaged Kwangmyongsong 4 again, during a zenith pass. I used an ISO 2500
setting this time and it registered well. The trails are still steady in brightness.

The UNHA 3 r/b is still flashing. I have noted that when it passes well west of
the meridian, the flashes are of much shorter duration than when it passes east
of the meridian or through the zenith. Did not have time to analyse yesterday's
flash period yet.
