Betelgeuse starting to brighten

An astronomers telegram has been issued as Betelgeuse started to brighten again in mid February. This appears consistent with the existing variability cycles though a deeper minimum than usual, probably due to overlapping cycles. It is still interesting and useful to observe with both photometry (visual and electronic) and spectroscopy. To verify the brightening continues as expected and to obtain more data on the behaviour on this interesting star.
