Spring is the season of day-time showers. If you’re operating a radio detector, look out for the many Arietid showers which peak in May and June and can have a combined rate of around 30: the eta Arietids (DEA) at 09:00UT on 9th May, the May Arietids (DMA) at 10:00UT on 16th May, the Daytime Arietids (ARI) at 10:00UT on 7th June plus the zeta Perseids (ZPE) at 12:00UT on the 9th of June.
The only major shower in May or June is the eta Aquariids (ETA) which peak early in the morning of 6th of May. The radiant rises just before dawn so it is best to observe in the early hours. A Visual rate of ten per hour is possible. There’s more about this shower here.
The June Bootids (JBO) have not been active for several years but if you see any enhanced activity between 23rd and 27th June, please let me know.
