Our cover picture ...
... shows a fireball on 24 May 2010, photographed at the observatory in Izaña (Tenerife), and proves that observing can be worthwhile outside the major showers as well. At 03:45:30 UT this −7m bright fireball flared up and moved quickly westward at 20°/s. It left a train that was visible for 20s. The red glowing dome visible in the picture belongs to the new GREGOR solar telescope. Its brightness is exaggerated by the camera sensor. The red LEDs belong to a measuring system that records the behavior of the flexible dome in wind. © Photo: Jürgen Rendtel
