A dip in brightness began Friday (2018 March 16). Here is the updated light curve as of an hour ago including two new measurements from TFN and ELP.
We now show these data in two graphs. The first is the full light curve from 2017 May until now. The second is a close up view showing the beginning of 2018 observing season until now. The profile of the new dip having a slow decline with a more rapid increase is again reminiscent to that of a backwards-comet (see last paragraph of Section 5.4 here).
