Notes.
Note that for 35 d cycle numbers 303 and larger the corresponding numbers in Staubert et al. (2007) are larger by 1. This reflects the observation that there must have been an extra cycle during the long anomalous low before cycle 303. However, using the numbers as given here allows to use them in an ephemeris for a rough prediction of the 35 d turn-ons using a mean period of 35.88 d. We do not doubt the physical reality of the extra cycle found by Staubert et al. (2007).
