Our front cover images all relate to Vilnius Astronomical Observatory in Lithuania, which achieved some prominence in the 1960s through 1990s when the ‘Vilnius photometric system’ was used by various international observatories for variable star research. This system was seen as an alternative to the Johnson UBV and Stromgren photometric systems. Vilnius Observatory had a vibrant evolving publication program to disseminate its research, and the paper by Agnė Poškienė, Carlos Viscasillas Vázquez and Šarūnas Mikolaitis on pages 329–350 in this issue of JAHH discusses the Bulletin of the Vilnius Astronomical Observatory, its predecessor (shown on our front cover) and its successors, Baltic Astronomy and eventually Open Astronomy (which is also shown on our cover).
