The front cover of BASIL celebrates the 80th anniversary of the Bristol Astronomical Society, showing the announcement in the Bristol Evening Post of 2 December 1942. Our first meeting was held in Cotham on 8 December 1942. Predicted solar activity, solar cycle progression, lunar phases and events, solar system finder charts and rise / set […]
The front cover of BASIL shows an image of the recent (25 October 2022) partial solar eclipse, taken by David Bennett (BAS) at the Cyril Swindin Observatory in Failand. Predicted solar activity, solar cycle progression, planetary observing notes, finder charts and rise / set times are reported for November. Solar activity continues to increase with […]
The front cover of BASIL shows an image of the Great Cygnus Wall, by BAS member Chris Lee. Predicted solar activity, solar cycle progression, planetary observing notes, finder charts and rise / set times are reported for October. Solar activity continues to increase with enhanced activity forecast due to Coronal Hole High Speed Streams (CH […]
The front cover of BASIL shows last month’s solar observing at Troopers Hill. Predicted solar activity, solar cycle progression, planetary observing notes, finder charts and rise / set times are reported for September. Constellation of the month is Pegasus, which is well placed for observing Messier 15 – a magnificent globular cluster. Visible transits of […]
The front cover of BASIL shows the Star Chair 3000, a motorised, joystick controlled binocular observing chair. The Star Chair 3000 was kindly donated to the BAS by Andy Stephens (a former Chair of the BAS) and the cover photo (top) shows Andy and Dave Bennett with the equipment. Predicted solar activity, solar cycle progression, […]
The front cover of BASIL shows Prof David Southwood giving the BAS Annual Presidential Address last month. The talk had the theme of exploring the icy moons of Jupiter and David gave the audience a fascinating insight into the development, planning and opportunities of the ESA JUICE Mission. Predicted solar activity, solar cycle progression, planetary […]
The front cover of BASIL shows an image of the bright star Arcturus (Alpha Boötis), which is well placed for observing in June. Solar cycle progression shows a marked upward trend in sunspot numbers over the year – predicted numbers are given for the next 12 months, as solar activity is forecast to increase. Planetary […]
The front cover of BASIL shows solar images and sunspots taken recently by BAS member Chris Lee. Solar cycle progression continues to show an upward trend in sunspot numbers over the year – predicted numbers are given for the next 12 months, as solar activity is forecast to slowly increase. Constellation of the month is […]
The front cover of BASIL shows a pale green image of the Moon, taken using an Ultra High Contrast filter by BAS member Andrew Grasemann. Solar cycle progression continues to show an upward trend in sunspot numbers over the year – predicted numbers are given for the next 12 months, as solar activity is forecast […]
The front cover of BASIL shows plans for a 3D printed model of the Society’s Cyril Swindin telescope, which is being prepared by BAS member Trevor Taylor. The Cyril Swindin telescope was a 12-inch Newtonian reflector telescope which was in the dome at our Failand Observatory for many years, prior to the installation of the […]
