The Aurora Borealis is set to appear over Ireland tonight.
Experts said the Northern Lights could potentially be seen anywhere in the country over the next few days.
However Astronomy Ireland's David Moore warned that it won't look exactly how many might be expecting.
He told Morning Ireland on RTE Radio One yesterday: "You see the colours in photographs but to the naked eye unless it's a very strong display, you usually only see a greyish and whitish colour in the sky.
"So people perhaps watching the 9pm news and looking at the beautiful greens and pinks, colour cameras are good at picking that up, but unless it's a major display its usually more of a whitish colour.
"This is not a huge storm that's expected, we never really know the intensity, so you might only be looking at a small glow on the northern horizon.
"We'll be seeing it from hundreds of kilometres away unless it moves very far south, which has happened in the past, so we can only hope for that, but look for a glow in the north, that's the tip.
"Normally we'd say a rural location would be good but unfortunately we have a full moon this week, so the moon will be quite bright.
"Even though we're predicting Tuesday night is the most likely time for the radiation of the sun to cause this aurora, there was actually a strong display last night and it could be tonight as well, or in fact over several nights.
"Don't just look tomorrow night, keep checking the sky."
And Mr Moore went on to say that, while the north may be slightly more likely to see the display, it can easily be seen anywhere in the country.
He added: "The North coast is slightly better favoured but people even in Kerry people shouldn't worry, Ireland is such a small island that it doesn't make much difference being on one end of this island to the other.
"The only advantage people on the North coast have is they're looking over the Atlantic ocean so there won't be any artificial lights in the distance that could trick you.
"Also it may be cloudy at the beginning but you can see this from dusk till dawn, so just keep checking the sky if you do have clouds."
Current forecast
The latest forecast from Met Eireann suggests cloud cover could ruin the view of the Northern Lights in some areas, particularly in the west coast as rain moves in from the Atlantic this evening.
However there is some hope, particularly in the early hours of tomorrow morning, as weather experts predict a clearing in the showers by dawn.
The full forecast reads: "Mainly dry this morning with mist and fog patches clearing and sunny spells developing. There'll be a few showers in the west. Rain will develop in the west in the late afternoon and spread over the western half of the country this evening. Highest temperatures of 13 to 15 degrees with moderate to fresh southerly winds, increasing strong and gusty near Atlantic coasts this evening.
"Early tonight, rain will continue to spread eastwards to all areas. It will be heavy at times with a risk of spot flooding. A clearance to showers move into the west by dawn. Southerly winds will be fresh and gusty and will be strong in coastal areas. Lowest temperatures of 9 to 12 degrees."
