Every day over 40,000kg of space dust enters the atmosphere. Most of this dust is microscopic and can't be seen, but a few larger pieces (=larger than a grain of sand) can be seen burning up in the atmosphere every hour. At certain, regular, times of the year there are more intense showers of meteors. The peak dates for the main meteor showers visible from Aberystwyth are listed on the right.

Many meteors can be seen days and even weeks either side of the peak activity. NASA's Fluxtimator forecasts the meteor shower rate for many annual showers. To use it you'll need to change the date and the location. (If you don't want to use London then enter 52°25'North 4°05'West for Aberystwyth)
