Update, 11.20am Saturday
CHRIS Wyatt has been gazing at the sky for 60 years and has only seen anything like the daytime phenomenon observed yesterday a couple of times.
He did not see yesterday's unusual streak of light but did notice the excitement on Twitter yesterday evening.
Because he did not see the event he could not tell if it was space junk or a meteor, but did say there was a way for those who did to tell what it was: a meteor would likely only be visible for less than a second.
Space junk moves more slowly than a meteor, which would only visiable for less than a second.
"Space junk might be visible for 10 or 12 seconds as it moves across the sky," Mr Wyatt said.
Most of the meteors that enter the earth's atmosphere are tiny, perhaps the size of a pea and are not visible from the ground, he said.
They need to be the size of a basketball before they become noticeable.
Mr Wyatt recommended anyone wishing to see another beautiful event in the sky take a look at the crescent moon, which would be visible over the next few days.
REPORTS of an unusual streak of light flitting through the sky are emerging in Victoria, including Bendigo.
Kylie McDonell saw a meteor in the sky south-west of Bendigo about 3.45pm today.
She was in Maiden Gully at the time.
Melbourne-based media outlets are also investigating similar reports.
Monash University School of Physics and Astronomy Associate Professor Michael Brown said possibilities included a meteor or space junk re-entry.
Based on the information available, the Astronomical Society of Australia member said a meteor was the most likely explanation.
More to come.
