Both series show, as does the graphic representation, with un- 
mistakable certainty a periodical variation of the brightness to an 
amount of about one scale-unit with a maximum on 4.8 August. 
The calculation of a sine-formula resulted in (zero epoch 3.0 August): 
1st series 4.08 + 0.45 sin (p — 72°0) Maximum 4.79 Aug. + 04.13 
gnd series 1.03 + 0.47 sin (y —78°9) Maximum 4.86 Aug. + 01.09
