TL;DR: The Southern Hemisphere Asteroid Radar Program (SHARP) as mentioned in this paper uses available antenna time on either a 70 or 34 m beam waveguide antenna located at the Canberra Deep Space Communication Complex (CDSCC) to transmit a Doppler compensated continuous radio wave at 2.114 GHz (14.2 cm) and 7.15945 GHz (4.2cm) toward the NEO and receive its echoes at the 64 m Parkes or 6 m × 22 m Australia Telescope Compact Array (ATCA) antennas at Narrabri in Australia.

TL;DR: The new meteor shower lambda -Sculptorids produced by comet 46P/Wirtanen was observed. The shower peaked at a zenithal hourly rate (ZHR) of $0.65^ $ meteors per hour. The mean mass of observed meteoroids was 0.5 g.

New Dimming Events in Southern R Coronae Borealis Stars
TL;DR: In this paper , the photometry of three Southern R Coronae Borealis (RCB) stars has been reported, and low resolution spectra of one of the targets indicates blueshifted Na'i D lines, and hydrogen alpha emission.

TL;DR: In this article, a coordinated program involving X-ray, ultraviolet, optical, and radio observations of the dM5e flare star Proxima Centauri was reported, and the authors concluded that the observed 20 min expotential cooling time is consistent with an electron density of 1.2-4.0 keV.
