New Comet P/2019 LM4 (Palomar)

CBET 4775 & MPEC 2020-J68, issued on 2020, May 14, announce that an apparently asteroidal object discovered on images taken at Palomar on 2019 June 4 and 7 with the 1.2-m f/2.4 Schmidt telescope (and given the minor-planet designation 2019 LM_4 when published on MPS 1001527, along with observations made elsewhere on June 8) has been re-discovered showing cometary appearance at two other observatories. The new comet has been designated P/2019 LM4 (Palomar).

New comet discovered by solar observatory

In late May and early June, Earthlings may be able to glimpse Comet SWAN. The comet is currently faintly visible to the unaided eye in the Southern Hemisphere just before sunrise. The new comet was first spotted in April 2020, by an amateur astronomer named Michael Mattiazzo using data from the SOHO satellite.

New Comet C/2020 H6 (ATLAS)

CBET 4768 & MPEC 2020-J23, issued on 2020, May 03, announce the discovery of a comet (magnitude ~18.5) on individual images from taken on Apr. 22 UT with a 0.5-m f/2 Schmidt reflector at Haleakala, Hawaii, in the course of the "Asteroid Terrestrial-Impact Last Alert System" (ATLAS) search program. The new comet has been designated C/2020 H6 (ATLAS).

Hubble captures breakup of comet ATLAS

The NASA/ESA Hubble Space Telescope has provided astronomers with the sharpest view yet of the breakup of Comet C/2019 Y4 (ATLAS). The telescope resolved roughly 30 fragments of the fragile comet on April 20 and 25 pieces on April 23.

Hubble probes Alien Comet's Chemical makeup

Astronomers have uncovered more than 4,000 planets that orbit stars outside our solar system. But they have few details on the planets' chemical makeup and how they were assembled inside a swirling disk of rock and ice encircling their stars. The stars are too far away for us ever to visit them and see the planet-making recipe close-up. Now, a sample from a distant star system has landed in our solar system's back yard. Comet Borisov, the first vagabond comet ever to enter our solar system, offers chemical clues to the composition of an object born around another star. Comets are made of gas, ice, and dust that are part of a planet's building blocks. Borisov's unusual abundance of carbon monoxide, as gleaned through Hubble ultraviolet spectroscopic observations, is largely unlike comets belonging to our solar system. Researchers say this abundance points to the comet originating from a circumstellar disk around a class of star called a cool red dwarf.

New Comet P/2020 G1 (Pimentel)

CBET 4754 & MPEC 2020-H06, issued on 2020, April 17, announce the discovery of a comet (magnitude ~15) by Eduardo Pimentel on CCD images taken by Jacques, Pimentel, and J. Barros with a 0.28-m f/2.2 astrograph of the "Southern Observatory for Near Earth Research" (SONEAR) at Oliveira, Brazil. The new comet has been designated P/2020 G1 (Pimentel).

New Comet C/2020 F8 (SWAN)

CBET 4750 & 4752 & MPEC 2020-G94, issued on 2020, April 13, announce the discovery of a comet (total magnitude ~8.5) by M. Mattiazzo in the low-resolution public website hydrogen Lyman-alpha images obtained with the Solar Wind Anisotropies (SWAN) camera on the Solar and Heliospheric Observer (SOHO) spacecraft. The new comet has been designated C/2020 F8 (SWAN).
