ZWO ASI Camera type keys
In order to unify the camera type abbreviation keys of all ZWO ASI camera models, we had to change some of the currently used camera type keys.
New Comet C/2020 K7 (PANSTARRS)
CBET 4790 & MPEC 2020-L09, issued on 2020, June 02, announce the discovery of a comet (magnitude ~20) in four 45-s w-band CCD images obtained with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala. The new comet has been designated C/2020 K7 (PANSTARRS).
Solar Orbiter to pass through the tails of Comet ATLAS
ESA's Solar Orbiter will cross through the tails of Comet ATLAS during the next few days. Although the recently launched spacecraft was not due to be taking science data at this time, mission experts have worked to ensure that the four most relevant instruments will be switched on during the unique encounter.
New Comet C/2020 K3 (Leonard)
CBET 4782 & MPEC 2020-K159, issued on 2020, May 25, announce the discovery of a comet (magnitude ~18) by G. J. Leonard on images taken on May 22 UT with the Catalina Sky Survey's 0.68-m Schmidt reflector. The new comet has been designated C/2020 K3 (Leonard).
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 J1 (SONEAR)
CBET 4769 & MPEC 2020-J37, issued on 2020, May 04, announce the discovery of a comet (magnitude ~17) on images taken with a 0.28-m f/2.2 astrograph of the "Southern Observatory for Near Earth Research" (SONEAR) at Oliveira, Brazil, on May 1 . The new comet has been designated C/2020 J1 (SONEAR).
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).
New Comet C/2020 H2 (Pruyne)
CBET 4761 & MPEC 2020-H220, issued on 2020, April 28, announce the discovery of a comet (magnitude ~16.5) by Theodore A. Pruyne on four 30-s CCD exposures taken with the Catalina Sky Survey's 0.68-m Schmidt telescope. The new comet has been designated C/2020 H2 (PRUYNE).
