This page lists our monthly meetings. For other events open to the general public, see our Events page
Dates are set well in advance but the 'content' of the meeting is only updated (from our 'meetings database') when details are entered, so 'blank' or 'TBA' may be shown when data has not yet been entered (please be assured that the meeting will take place and a talk on (some) Subject will be delivered by (some) Speaker ! )
Meetings are held at the Church Hall (aka 'The Soltau Center') of St James-the-Less, Stubbings, Maidenhead SL6 6QW, from 7.30 (for a map and directions, see the About MAS (Where we meet) page
The Main Topic is usually delivered by an invited guest speaker. We aim to provide a diverse range of subjects linked (in some way) to Astronomy - whilst the 'Second Session' is typically delivered by one of our members. If time allows, the evening concludes with a short 'What to see this month'.
Details of a typical evening (times are approximate) :- 7.30pm. The evening starts with the Chairman delivering any important Announcements and then introducing the main speaker. 7.45pm (latest). Main Topic Speaker gets up and the lights are turned off. If you arrive after 7.45, please enter the Hall by the first door (on the right, after the entrance) and please be extra careful when finding a seat at the back of the Hall as members often setup telescopes there ! 8.45-9pm +. Coffee break during which visitors often chat with members who have set-up their telescopes at the back of the hall. If the weather is good, sometimes members will nip out for a quick look at the sky. Smoking is permitted outside the Hall, however smokers are asked to avoid any 'observers' (smoke particles always seem to get into optical equipment, no matter how well 'sealed' it may be) 9.15pm (at the latest). The 'Second Session' then runs for about 45 mins, typically ending with "What's Up !" (what to look out for in the sky this month) 10pm. We aim to clear the hall by 10pm. Post meeting Observing. If the weather is good, the Observing Organiser then leads the way to our chosen observing site, or (if the weather looks even a slight bit 'iffy) members sneak off to the local Pub instead :-)
Next meeting :
(+) 5 Apr 2019 Space Weather - (Dr Colin Forsyth)
(+) 3 May 2019 To be announced
(+) 7 Jun 2019 MAS 61st AGM
(+) Jul 2019 Summer break - (no meeting)
(+) Aug 2019 Summer break - (no meeting)
The meetings archive gives an 'overview' of the Society activities over the past 10 years (see also the Events page).
Members have access to the full 'History of MAS' (including AGM minutes going back to 1957) along with full names and photos
The MAS 'year' runs from September of one year to June of the following. The end of year AGM in June elects the Committee for the following year (there are no meetings in July and August - although often members will meet informally at the local pub - which gives the new Committee time to 'get a grip' on running the Society)
The "short cuts" (in the 'title bar', at the very top of this page) will take you to the June AGM entry for the end of that MAS year

Friday, 7th April 2017 - Comets by Kenelm England
Kenelm gave us a very interesting talk, focused on the comet 41P/Tuttle-Giacobini-Kresak, which, over the next 2 days, will be as close to the Earth as it will ever be.
41P has a very interesting history, having first been discovered on May 3, 1859 by Horace Parnell Tuttle (who was a prolific Comet hunter, who found over a dozen Comets). It's orbit was calculated as parabolic, so he was not surprised when it was not seen again.
On 1st Jun 1907, Michel Giacobini sighted what he thought was a new comet. Visible until June 14, it's orbit was again calculated as parabolic.
However, in 1928, Andrew Crommelin connected the 1859 Tuttle and 1907 Giacobini sightings as the same comet and it's orbit of 5.5 years. However, despite a search 41P was not seen in either 1928 nor in 1934.
On April 24, 1951, 41P was found by Lubor Kresak. After coming as close as (just under) 0.5 AU to the Earth, it was last see on Aug 9. This allowed it's orbit to be calculated as 5.47 years.
41P/Tuttle-Giacobini-Kresak was next seen on Jan 28 1962, coming as close as 0.266 AU and last sen on Aug. 5. This allowed it's orbit to be confirmed and established that it would only be visible 'every other visit' (as it would appear on the other side of the Sun between between sightings).
This was conformed when it was next seen on 8th Jan. 1973, at mag. 21, reaching mag 14 on may 20. However, unlike previous visits, during the next 6 days it brightened to mag 8, and then in 1 day suddenly brightened to mag. 4 ! It then faded to mag 14 by end of June and was last seen on Sept. 23.
The following two occasions, in 1995 and 2001 it peaked at mag 7, but in 2006 was back to mag 10.
Now (7th April 2017), it is at mag. 8.3 and can be seen in binoculars to the right of the square of Ursa Minor (having passed through the square of Ursa Major). It is now starting to recede from the Earth, having just made it's closest approach 'ever' (Jupiter will kick it further away from the Earth on it's next and subsequent orbits).
Observers should keep a keen look-out over the next month or two, just in case it 'flares up' to become a naked eye object !
