Most of them were taken as bad omen. I have a book on the Halley comet by astronomer Paolo Maffei who narrates how people in Florence waited for the comet in May 1910 eating salami and drinking Chianti because astronomer Camille Flammarion had predicted that the gases in its tail would kill them. But nothing bad happened.

This one might be the Covid-19 bad omen comet.

Lets hope it is not a harbinger of bad news.

Asteroid 1998 OR2 will pass today at 6.3 million km from Earth. It is a large asteroid, about 2 km wide but will be not a danger. I am running Asteroids@home in Science United, both on CPU and GPU.

So am I, but running Asteroids@home only on GPUs.

CPUs are running on Rosetta@home (for COVID-19) & on WCG (also, looking forward towards OPN1 against COVID-19).

Actually checked the sky just now. Yes Venus was there. But it's very hard to find even star constellations. So where is that comet now?

It's still there, but dimmed:

I now checked again but not knowing in what direction I should at look at. Some says the comet is between Polaris and Ursa Major. Cant' see any of them. Venus is of course out of sight now....

People in Florence gathered on Piazzale Michelangelo overlooking Florence with ample supplies of bread, salami and Chianti flasks on the night of May 19 1910 to prepare for every outcome. They were disappointed when nothing happened.

I have a book by astronomer Paolo Maffei on comets and he writes that comets have always been associated with evil events. At the passage of Halley comet in 1910 there were fears that gases in its tail would exterminate mankind but nothing happened. Astronomer Camille Flammarion wrote about these fears, denying them.

I don't think we have to buy Anti-comet pills this time:)

COMET ATLAS MIGHT BE FRAGMENTING: Comet ATLAS (C/2019 Y4), what are you doing? New data from astronomers around the world show that the once-promising comet is beginning to fade.

On April 6th, astronomers Quanzhi Ye of the University of Maryland) and Qicheng Zhang of Caltech reported new images of Comet ATLAS, in which the comet's core appears to be elongating--"as would be expected from a major disruption of the nucleus,"

"Finally, let's not forget that ATLAS is a fragment of a larger (unidentified) comet also related to the Great Comet of 1844," says Battams. "Fragmenting is a family trait for these guys."

I doubt that it will be visible for a naked eye.
Anyway the comet passes closest to the Sun around on Sunday, 31 May so around that date it may will be possible to see the tail.

A Great Comet? A harbinger of ... . Arrives in the middle of virus. The conspiracy theory guys will have a field day.

Comet Y4 Atlas in Outburst: First Good Comet for 2020?

Good news: Though we’ve been going through a cometary dry spell as of late, we may have our first good naked eye comet for 2020: Comet C/2019 Y4 ATLAS.

Discovered by the ATLAS (Asteroid Terrestrial-impact Last Alert System) survey on the evening of December 28th, 2019, Comet Y4 ATLAS was the last comet discovery of 2019. Though it was only at magnitude +19.6 at the time of discovery, the orbit of Y4 ATLAS is intriguing, bringing it in just 0.262 AU (39.2 million kilometers or 24.4 million miles) from the Sun in late May 2020. That’s interior to Mercury at perihelion, at 0.307 AU from the Sun. This comet also grabbed observer’s attention in January 2020 when it jumped 5 magnitudes to +12, or 100-fold in brightness.

There is a comet near Venus in the evening. It should brighten like Venus in May.

Asteroids come in all shapes and sizes, and now astronomers at MIT and elsewhere have observed an asteroid so heavily cratered that they are dubbing it the “golf ball asteroid.”

The asteroid is named Pallas, after the Greek goddess of wisdom, and was originally discovered in 1802. Pallas is the third largest object in the asteroid belt, and is about one-seventh the size of the moon. For centuries, astronomers have noticed that the asteroid orbits along a significantly tilted track compared with the majority of objects in the asteroid belt, though the reason for its incline remains a mystery.

US meteorite adds to origins mystery
https://www.bbc.com/news/science-environment-50419924

In January 2018, a falling meteorite created a bright fireball that arced over the outskirts of Detroit, Michigan, followed by loud sonic booms.

The visitor not only dropped a slew of meteorites over the snow-covered ground, it also provided information about its extra-terrestrial source.

Although tens of thousands of meteorites have been recovered by humans, scientists have only been able to trace the orbits of a small number. Most of these have been calculated in the last decade.
