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

Meeting 1 April 2016
Report by Steve B
"The Universe in Multiple Wavelengths" by Jim House
Jim explained how Astronomers split up the electromagnetic spectrum (which runs from the low energy long wavelength radio waves to the highly energetic ultra-short cosmic waves) into overlapping 'bands' that require very different instruments to 'image'.
Of course, as astronomers we are mainly interested in the visible wavelength 'band', which overlaps into the Infra-red (and less so into the ultra-violet) - so his talk concentrated on the other wavelengths !
The Infra-red band was discovered first, when ?? used as prism to split light and found 'invisible' radiation to the left of red was heating a thermometer.
Ultra-violet took a little longer, however ?? heard about the discovery of IR and specifically looked for 'something'; to the right of blue- and when nothing showed up when he used thermometers he used photographic chemicals (specifically, silver iodide).
Jim then showed us a image of the crab Nebula in visible light and, as he talked about each wavelength 'band', showed us a corresponding image of the nebula 'taken' in that band.
Of course the 'problem' with longer wavelengths is obtaining reasonable 'resolution' - and this required 'long base line' interferometry, first demonstrated in ??? using surplus WW2 radar equipment (MAS members will remember our trip to Mullard Cavendish Laboratory, Cambridge)
2nd half - "Gravitational Wave Astronomy: The Beginning of a New Era" by Martin Dyer
Martin started by mentioning how he was inspired by one of our Star Gazing Live events to take up Astronomy, so mush so that he is now studying for a Doctorate in Astronomy !
He next explained how Einsteins equations 'predicted' the existence of Gravity Waves and even allowed their 'characteristics' to be defined to the point where it was possible to design a detector, based on a 'scaled up' Michelson Interferometer, of which two are operational (both in USA, LIGO H1 is in Washington state, LIGO L1 in Louisiana)
The first Gravity wave (GW150914) was detected by both detectors (one of which was not even due to go 'on-line' at the time) eliminating all possibility of 'noise' as the cause.
The characteristics of the wave allowed the 'source' to be determined as a pair of black holes, one 35 times the mass of the sun, the other slightly smaller, that circled around each other starting at 30 times a second. By the end of the 20 millisecond wave, the two had accelerated to 250 times a second before the final collision.
The delay time between the two detectors even allowed astronomers to establish the direction of the wave (as a 'ring' = a 3rd detector being required for 'triangulation') and it's distance (about 1.3bn LY), however although telescopes have scanned the sky at these locations nothing has (yet) been seen in the optical wavelengths.
Martin's doctorate involves the construction of a 'wide field' telescope, built using 8 'off-the-shelf' Newtonian reflectors, with high resolution cameras, which should allow will allow 'fast response' and detection of the optical counterpart when the next Gravity wave is detected.

(presented by Steve)
Robin, who was off skiing, was good enough to leave me a Stellarium 'script' of 'What to look for in April'. This focused on the constellation of Leo, which can be found more or less due South after midnight by the middle of the month.
Needless to say, my PC managed to 'loose' the ground (it substituted a very nice sea-scape :-) ) and showed times 1Hr 'out' compared to Robin's script text (I'm guessing he set-up the script before the clocks went back :-) )
Of course, I had no idea how to pronounce the names of the various stars 'highlighted' by the script, however it did run OK and the various DSO's were shown up very well along with a 'overview' that would help to find them.
The script was somewhat less successful in showing where the Planets could be found - the Moon, was fine, more of less directly below Leo (which also helps the observer locate Leo :-) ), as was Jupiter (also to be found 'below' Leo, but generally 'to the left' (East) of the Moon). However Saturn and Mars were shown far too 'zoomed in' with little visibility of the surrounding constellations to make location 'easy', especially as I has no idea where to find them so was unable to enlighten anyone :-)
No doubt members will be very glad when Robin returns next month !
