  3. https://arxiv.org/abs/2005.02541 A naked-eye triple system with a nonaccreting black hole in the inner binary HR 6819 The radial-velocity semi-amplitude of 61.3 km/s of the inner star and its minimum (probable) mass of 5.0 Msun (6.3 +- 0.7 Msun) imply a mass of the unseen object of >= 4.2 Msun (>= 5.0 +- 0.4 Msun), that is, a black hole (BH).

    C/2020 F8 https://www.spaceweather.com/archive.php?view=1&day=19&month=04&year=2020 The case for Comet SWAN being a hyperbolic comet is not ironclad. Based on an observation arc of only 3 days, JPL reports the eccentricity of SWAN's orbit as 1.1 +/- 0.2. The error bars are still large. The uncertainties will shrink, however, as more observations are added to the database in the nights ahead. Stay tuned for updates.
