A “spectacular” meteor shower is expected to light up the night sky this weekend.
The Geminid shower, which is referred to as a “meteor storm” because of its intensity, is forecast to peak sometime between Saturday and Sunday.
The shower has been known to produce more than 150 meteors per hour at its peak, but due to light pollution and other factors the number seen is usually considerably less.
The Geminids originate from a rocky asteroid called 3200 Phaethon with a comet-like orbit and were first observed in 1862.
Dr Minjae Kim, a research fellow in the physics department at the University of Warwick, said: “The Geminids are one of the most spectacular meteor showers of the year.
“They are fascinating as they’re one of the few major meteor showers associated with an asteroid 3200 Phaethon rather than a comet.”
According to the Royal Observatory in Greenwich, the bright meteors of the Geminid shower are unusual in that they are multi-coloured, with most of them being white but some being yellow and a few green, red and blue.
The colours are partly caused by the presence of traces of metals such as sodium and calcium, the same effect that is used to make fireworks colourful.
The meteors, small pieces of interplanetary debris, appear to radiate from near the bright star Castor in the constellation Gemini.
While the shower can be observed with the naked eye, it is recommended stargazers ready themselves for some time outside as it may take a while for them to observe the spectacular streaks.
Those hoping to catch a glimpse are advised to find a wide open space away from sources of light pollution.
British Transport Police held an emergency exercise for press officers in March, which ironically involved a stabbing on a train travelling south near Huntingdon.
In the training drill, the train stopped immediately between stations when a passenger pulled the emergency cord.
It took police 25 minutes to reach the train and casualties, far longer than the eight minutes in which Cambridgeshire firearms officers reached the scene at Huntingdon station.
Chris Webb, a crisis communications expert who helped run the exercise, said: “People think if you pull the emergency cord on a train it stops immediately, but that’s not what happens these days.
“As soon as the driver knows there is a problem, he or she radios the line operator HQ and they discuss where to stop.
“The decision last night was to keep going to Huntingdon station, where it was much easier for armed police to get on.”

He added: “It must have been awful for passengers when the train kept going for another ten minutes or so.
“It’s always a balance. It might have prolonged the attack, but stopping in the middle of nowhere can mean the attack stops but it’s much more difficult for the emergency services to get there.”
Mr Webb, former head of news at Scotland Yard, said such exercises are held regularly by train operators.
A similar drill was carried out on the London Underground weeks before the 7/7 bombings in 2005.
“There are always lessons to learn but you cannot guard against everything.”
In the training exercise in March the suspect was a white man with mental health issues. He was shot dead by police.

Police triggered the Plato code to all emergency services in their initial response to the Huntingdon train stabbing, but that did not label it a terrorist attack.
Plato is called for a major incident where it’s thought a suspect is on the loose and has already, or is liable to, cause serious injury.
Plato does not denote a terror attack, though it is often used in terrorist incidents.

In a Plato response paramedics, fire fighters and other first responders are sent to a safe rendezvous point while armed police go in and deal with the suspect.
Plato depicts a situation where unarmed responders are vulnerable and are kept back until it is safe to approach casualties.
There are exceptions and it’s understood the East of England Ambulance Service has a special Hazardous Area Response Team (HART) which was allowed to accompany armed police onto the platform where the two suspects were arrested last night.
Once other first responders were allowed in, Plato was called off – an important part of the operation.
Plato was called during the initial response to the Manchester Arena bomb attack in 2017, but the fire service was not told it had been called off for two hours and that meant its officers did not go in to help with the rescue.
A student has told how she thought she “was going to die” during a mass stabbing on board a high-speed train.
Amira Ostalski was travelling to London for a Saturday night out with her friend Vanessa on board the “very busy” 6.25pm Doncaster to King’s Cross LNER service.
She told Sky News correspondent Dan Whitehead they were “listening to music, just having a good time”, when “panic and chaos” broke out in her carriage, Coach G, between Peterborough and Huntingdon.
“I see five rows ahead of us a guy in a white t-shirt just jumps out of his seat,” she said. “People are screaming, ‘he’s got a knife’…. I’m guessing he stabbed the person right in front of me.”
Ms Ostalski said she came within 2m of the attacker but only caught a glimpse of him adding: “He was just a black bearded guy wearing all black and a hoody.

“I didn’t see the knife he was holding. I’m guessing because it was already in the body or something.”
She said she “started running” and was “trying to calm everyone down” because there was a young boy, around six years old, who hid in the toilets with his mum.
“Everyone’s running. A guy next to me is holding his arm saying he’s been stabbed. He was running. I see people covered in blood,” she said.
“Everyone was shocked, everyone was terrified. People wanted to know what was going on, everyone’s pushing and shoving. Everyone’s getting trampled.”

Ms Ostalski said she heard some people crying on the phone “in tears and in shock, thinking they’re going to be stabbed”.
“It was horrific, it was really horrific because we had no idea where he was and the conductor who tried to stop him, he got stabbed as well.
“We felt that we were not safe because we were trying to get the train to stop but it wasn’t stopping.”

Ms Ostalski said she ran into the buffet car where she picked up a metal tray to protect herself and her friend.
“I was honestly so petrified. I thought in that moment it was the last time I was ever going to be alive. I thought I was going to die,” she said.
Ms Ostalski said she saw the attacker again when the train was stopped at Huntingdon station by the door, holding a bottle in his left hand.
“He just looked so calm and I think that was the most terrifying thing,” she said.

Armed officers were seen running along the platform at Huntingdon station towards the train carriages after multiple people were stabbed on board.

Police declared a major incident and armed officers can be seen in video footage sprinting along the platform.
Ms Ostalski said she thought she and the other passengers were safe when the train was evacuated.
But when she reached the car park, she turned around and saw the attacker jump the fence and start coming towards them.
“I have to admit, the police came really quickly and managed to detain him,” she said.
“I saw them running then took the knife and he got tasered and fell right on the spot.”
Two men born in Britain have been arrested over the attack, which police do not believe was motivated by terrorism, but Ms Ostalski said she only saw one of them.
A total of 11 people have been treated in hospital for their injuries, while two people remain in a life-threatening condition.
Ms Ostalski said she finally found safety in a taxi but will remember the ordeal for the rest of her life.
“Honestly, I’m scared to sit on a train,” she added.
A passenger who witnessed a mass stabbing on board a high-speed train heading for London told Sky News he heard someone yelling: “They’ve got a knife. I’ve been stabbed.”
The witness, who gave his name as Gavin, said there were “extremely bloodied” people and police shouting “get down, get down!” as passengers scrambled to leave the train.

Chief Superintendent Chris Casey of British Transport Police said: “This is a shocking incident and first and foremost my thoughts are with those who have been injured this evening and their families.
“We’re conducting urgent enquiries to establish what has happened, and it could take some time before we are in a position to confirm anything further.
“At this early stage, it would not be appropriate to speculate on the causes of the incident.
“Our response is ongoing at the station and will be for some time.”
