AZI (°) (at least): ~ most extents through cloud gaps:
to W: 310 - 335, to N: 340 - 360
 ! all through cloud gaps only !
at begin larger gaps, later most often 7/8 + higher gaps above 10° in height; no chances in the morning (early OSWIN...)
 *automatic camera observations 285 - 335 (21:06 - 00:15 UT) + 340 - 030 (21:54 - 00:11 UT);
visual inspection around 00 UT = almost 8/8
