A fireball seen shooting through the skies above parts of Ireland on Wednesday evening has been captured on Dublin Bay webcam, passing over Dublin Bay and Dun Laoghaire Harbour. 

The fireball was a meteor, experts have said. The observed portion of the trajectory covered over 300 km.

It appeared high in the sky at Dun Laoghaire for just a few seconds. before 10 pm and appeared to plunge seawards in flashes of light green colours to observers on the south Dublin Bay shoreline. 

The UK Meteor Network said it had received almost 800 reports after the blazing orb that was spotted in the night sky over Ireland, Northern Ireland and Scotland on Wednesday evening.

The UK scientists said the object, which lasted more than 20 seconds, was "definitely a meteor", adding "we are now 100% confident this was a small part of an asteroid".

The network said the end of the meteor's journey was not observed on camera, but that it ended over the north Atlantic Ocean, some 50-100km west of the Isle of Islay, the southern-most island of the Inner Hebrides.

An updated tweet from the organisation read: "It (the meteor) came on an asteroidal orbit and entered the atmosphere at 14.2 km/s.

"The observed portion of the trajectory covered over 300 km.

"If any meteorites did fall, they ended up in the ocean."

About Electric outboard engines

The direct-drive component in electric outboard engines means that the electric motors are incredibly efficient compared to conventional marine combustion motors, operating with considerably higher torque whilst using less power.

Without any need for gears, cooling systems and moving parts the motors are maintenance free, highly efficient and economic to run.

As a result, electric boat engines are becoming more popular on Irish waters as the world transitions from fossil fuels to green energy.

To date, popular electric engine sizes have been trolling engines typically used by fishermen on lakes.

These marine engines are available in models that can be used in fresh water and sea water, for your boat or kayak.

Electric motors are Ideal for fishermen because they are quiet and create little in the way of disturbance 

Popular electric trolling models range from 30lb thrust to 55lb thrust in a range of shaft lengths.

But use is becoming broader now in 2021 and electric outboard engines are being used on small runabouts and RIBS where electric outboard engine sizes are getting bigger.

Outboard electric engines are economical and environmentally friendly. Battery technology is also improving at a rapid rate meaning they are becoming smaller and lighter and run for longer.

Built in hydro-generation provides alternative recharging options whilst under sail are also options meaning the electric outboard now has a home on the stern on small yachts and dayboats too.

As far back as 2014, Torqeedo owner Jack O'Keefe from Cork Harbour told Afloat readers of his sailing adventures in a Drascombe Coaster dinghy and how after swapping from a petrol version the rewards from his new electric outboard engine are less noise, no smells, more stowage, better sailing performance and a motor that can be started by a small child. But it's still not silent, there's a whine he says here 

Popular brands in Ireland are Torqeedo, ePropulsion, Pulsar and Minn Kota but there are more arriving all the time as the technology advances
