automatic observation only during brightest NLC period; visual inspection at the end showed only very faint NLC
AZI at least ~ 303° (obviously before 303°) - 330°, not easy to say if there were NLC more to E because of reduced visibility due to Ci / dust stripes; in general good visibility with a bit haze/mist and Ci (most contrails);
no NLC detection on camera which observed the N-sector
