Proxima Centauri is our closest stellar neighbor and it is the smallest member
of the Alpha Centauri stellar system. With only 0.1\% of the luminosity of the
Sun, the orbits of rocky planets that could support liquid water, known as the
star's habitable zone, are located very close to it. The re-analysis of historic and recent high cadence observations with UVES and HARPS indicated the presence of a Doppler signal consistent with a small planet with a period between 10 and 20 days (the habitable zone of the star). However, due to strongly uneven sampling and contamination by stellar activity, a unique solution could not be derived. The Pale Red Dot campaign was a new observing run of ~60 consecutive nights (Jan 20, Apr 1st) with the HARPS/ESO spectrograph (1xspec/night) and simultaneous photometric follow-up in 4 photometric bands with the ASH2/Atacama telescope and telescopes of the LCOGT network. An outreach campaign supported by ESO and some other institutes allowed to broadcast the two months of the data-aquisition process and release invited articles from exoplanet experts abroad.
