Next Meeting: Christmas Party and Observing Event. Wednesday 13 December 2017.
Our Annual Christmas Party! And all for FREE! It’s family-friendly and above all FUN!!

IMPORTANT: Please note that the BSIA December meeting has been postponed due to the weather-related issues. Our raffle, and our next meeting, will now take place in early January, date to be confirmed.

To bring you the best star party experiences, we operate a floating date scheme, whereby the meeting may be moved at short notice. Naturally we target the day with the best weather outlook, but we also take into account special events in the sky, such as meteor showers, eclipses and transits. Occasionally the date will be set firmly to coincide with an event we can’t necessarily move; for example if a special guest is visiting us, or we’re holding our Christmas party!


Traditionally, the meetings have fallen on Wednesdays, but an evening either side, determined by the likely weather, has proven to be just as convenient and popular. As such, our current scheme allows us to pick any midweek three day window with a final announcement to be made a few days earlier. The announcement will always be sent out to our mailing list (which you can join here) and on Twitter and our Facebook group

Sometimes, we just can’t get a break. The week just looks awful. In extreme cases, we might outright cancel a meeting. It doesn’t happen often, and we’ll usually just postpone and try the following week. However, in the majority of cases, we go ahead anyway. Provided it’s not raining, we gather even under cloudy skies and enjoy an evening of social astronomy chat. Often this results in rewards for those who choose to attend, as London’s unpredictable cloud cover can vanish without warning – then it’s every telescope for itself! We highly recommend coming along even if it looks cloudy. Even if the sky has nothing to show us, there’s always something interesting to see and hear at one of our star parties.

Additional information on directions to the hub and our event etiquette is available.
