Rare Appearance of Two Comets in SOHO/LASCO C2 Field of View January 18, 2021.

It is rare to see two comets moving in the SOHO/LASCO C2 Field of View. That occurred on January 18, 2021. In this annotated image, arrows point out the two comets. The brighter object is a member of the Kreutz group of sun grazing comets. Both objects show tails extending away from the sun. BothContinue reading “Rare Appearance of Two Comets in SOHO/LASCO C2 Field of View January 18, 2021.”

Comet C/2021 A1 (Leonard) Sky Path in 2021

At discovery on January 3, 2021, new comet C/2021 A1 (Leonard) was located in the northern constellation of Canes Venatici (CVn) and moving northward in that constellation in January 2021.For most of the year 2021, comet C/2021 A1 is expected to remain at high northern declinations. Depending on your latitude, the comet may be circumpolar,Continue reading “Comet C/2021 A1 (Leonard) Sky Path in 2021”

Goldstone Delay Doppler Radar Images of (153201) 2000 WO107 Suggest a Bi-lobate Contact Binary Object

This sequence of delay doppler radar images of (153201) 2000 WO107 in November 2020 show an object like a bowling pin, a bilobate object or contact binary rotating slowly. It completes half of a revolution between 03:37:15 UTC and 12:13:32 UTC in the top left frames or 2.6 hours. The rotational period is approximately 5.2Continue reading “Goldstone Delay Doppler Radar Images of (153201) 2000 WO107 Suggest a Bi-lobate Contact Binary Object”
