The International Space Station (ISS) is passing over Ireland from now till Monday the 30th of March. Its magnitude is estimated to be between 1 and -2 , pretty bright, but you might be the lucky one to see it flaring to super-Venus levels!
On 21 of March, observers in the Netherlands saw the ISS's luminosity reach magnitude -6: four times brighter than Venus and 40 times brighter than Sirius, the brightest star in the sky.
"The bright flash is sunlight glinting off the station's enormous solar arrays. On March 20th, astronauts unfurled a new pair of arrays on the space station's starboard side, adding 8000 sq. feet of light-catching surface area to the station's profile. The extra area increases both the chances and the luminosity of ISS flares." - as we learn from spaceweather.com
