3/11 #ProximaCentauri has been monitored for 16 years, with no success of finding a planet
4/11 However there were hints of a signal between 10-20 days
https://palereddot.org/the-signal/ #palereddot
5/11 #palereddot observed #ProximaCentauri for 60 nights in a row with HARPS, ASH2 and @lcogt
6/11 #palereddot had a 90% success rate (54/60 nights) thanks to very good weather!!
7/11 #palereddot observations of #ProximaCentauri find a signal that is consistent with previous 16 years of data.
8/11 #palereddot team confirm the Doppler signal and are sure it is not caused by activity on #ProximaCentauri

9/11 #palereddot data is best interpreted by the presence of a planet
