When it is sunset it is also star rise and when is star set is also sunrise with just that short period of dawn and twilight when it is neither.

As a package it is one rotation to the central Sun and although we inherit the timekeeping aspect as one 24 hour day where these events follow one after another in respect to each rotation, why humanity chooses to insult itself or rather those who call themselves astronomers, cosmologists, planetologists or some other term can't bring themselves to promote it due to a silly mistake made centuries ago -

I worked a lot on the orbital motion to the Sun and how the stars appear to move from left to right of the same central Sun as we look out into the inner solar system -

If men can't love what is in front of them then truly they are no men.

Completely wrong! Sirius is visible long after sunrise and before sunset

I knew Colin and he told me he eventually found he was not the first to see
Sirius in the daylight. An English female astronomer had reported this in
the 19th century.

People are surprised about the brexiteers and their disruptive convictions but I am not, I just see more of the same for the last two decades and especially when you affirmed that the stars would appear to change position from left to right of the Sun due solely to the orbital motion of the Earth -

https://sohowww.nascom.nasa.gov/data...current_c3.gif

That timelapse, happening right now, is what we see minus daily rotation including stellar circumpolar motion - a clear view of the inner solar system inclusive of our orbital motion and presently the direct motion of Mercury as it moves out from behind the central Sun until it reaches it widest point before moving in the opposite direction.

Daylight when the Sun is in view and we look towards the inner solar system and the sacred darkness when we look in the opposite direction when the stars are visible represent a single package corresponding to one rotation and a thousand rotations in a thousand daylight/darkness cycle.

Don't come to me with your Colin, this is the realm of people like Copernicus and Galileo and their works.

Good that you brought up Sirius, anyone today can make a judgement call that Sirius comes out from behind the glare of the Sun as it moves parallel to the orbital plane due solely to the Earth's orbital motion -

https://apod.nasa.gov/apod/ap181123.html

https://sohowww.nascom.nasa.gov/data...current_c3.gif


I was taking a looser approach that we look towards the inner solar system when the central and stationary Sun is in view and to the outer solar system when darkness and the stars are in view -

https://img.purch.com/h/1000/aHR0cDo...xreS13YXkuanBn

https://i.kinja-img.com/gawker-media...prb1wpcjpg.jpg

All made possible by one rotation each 24 hour day despite 20 years of people here insisting more rotations than 24 hour days due to their addiction to stellar circumpolar motion (RA/Dec).

I didn't know the Soho/Lasco imaging was available otherwise I would have used it years ago but apart from that, what existed in written descriptions can be seen now in actuality.

Nothing difficult about seeing Sirius in the daylight. You lust need to
know where to look and have a clear sky. So everything you wrote about the
sun going down and the stars rising was wrong, Stars rise (or to be
accurate appear) to rise once
a sidereal day . But in the daytime they are hard to see unless they are
very bright. But they’re still there. They also set once a sidereal day.
And if you try hard you too will be able to observe Sirius in the daytime.
Colin Henshaw did this in Zimbabwe where the skies are very clear but as
I’ve already written it was also reported long ago from England.

This is just plain not true for the *northern* hemisphere and
*realistic* observation conditions. As Henshaw wrote, too.

It's not _easy_, but it's perfectly doable without huge effort. I've
seen Venus, Jupiter, Saturn, Mars, and Sirius in full daylight at 38°
N. The latter, three times.

Well, I've seen Sirius at noon before, and also Jupiter and Saturn. You just need a really good computer and drive on the telescope.

Nobody claimed that it would be easy except Mike Collins, based on
superficial reading of his source, at best.

Nobody claimed that it would be impossible either.
