The Toronto Magnetic and Meteorological Observatory is a historical observatory located on the grounds of the University of Toronto , in Toronto , Ontario , Canada . The original building was constructed in 1840 as part of a worldwide research project run by Edward Sabine to determine the cause of fluctuations in magn... |

Compasses tended to " wander " from north when measurements were taken at different locations or even at a single location over a period of time . The astronomer Edmund Halley noted this and the problems it would cause for navigation in 1701 . It was also believed that whatever was causing this effect might be causing... |
In 1833 the British Association for the Advancement of Science commissioned a series of magnetic measurements across the United Kingdom . Under the direction of Major Edward Sabine of the Royal Artillery , a multi @-@ year measuring project began , with the results to be published in 1838 . As the measurements were be... |
In 1837 , the British Government funded the installation of a magnetic observatory at Greenwich . The Association continued to press for the construction of similar observatories around the world , and in 1838 their suggestions were accepted by the Government and funds were provided . In 1839 the British Government an... |
The observatory , officially " Her Majesty 's Magnetical and Meteorological Observatory at Toronto " , was completed the following year . It consisted of two log buildings , one for the magnetic instruments and the other a smaller semi @-@ buried building nearby for " experimental determinations " . The north end of t... |
Using the measurements from the Toronto and Hobart sites , Sabine noticed both short @-@ term fluctuations in magnetic declination over a period of hours , and longer @-@ term variations over months . He quickly concluded that the short term variations were due to the day / night cycle , while the longer term ones wer... |
Sir John Henry Lefroy , a pioneer in the study of terrestrial magnetism served as director of the magnetic observatory from 1842 to 1853 ; In 1960 , the Ontario Heritage Foundation , Ministry of Citizenship and Culture erected a Provincial Military Plaque in his honour on the University of Toronto campus .

In 1853 the Royal Society 's project was concluded , and the observatory was set to be abandoned . After a lengthy debate , the fledgling colonial government decided to take over its operation . Rather than disappearing like its three counterparts , the Toronto observatory was upgraded , and its mission was expanded a... |
The new building was designed in 1853 by local architect Frederick Cumberland , who was also working on the design of University College , which was being built just north of the Observatory to replace King 's College . The new observatory design called for a stone building , with an attached tower containing the theo... |
During its time as a meteorological station , the observatory collected reports from 312 observation stations in Canada and another 36 in the United States . Each station was equipped with a " Mercurial Barometer , two Thermometers ( a maximum and a minimum Thermometer ) , an Anemometer to measure the velocity of the ... |
Among its other uses , in 1880 , measurements from the site were used as part of the effort to develop standard time . The observatory remained the official timekeeper for Canada until 1905 , when that responsibility was transferred to Ottawa 's Dominion Observatory . At exactly 11 : 55 am the clocks in Toronto fire h... |
In 1881 the observatory 's director , Charles Carpmeal , suggested adding a high @-@ quality telescope to the observatory . He felt that direct solar observations would lead to a better understanding of sunspot effects on weather ( as late as 1910 the observatory 's then @-@ director , R. F. Stupart , noted that " sun... |
Funds were provided for the purchase of a 6 @-@ inch ( 150 mm ) refracting telescope from T. Cooke & Sons . The dome was originally designed to mount a small transit , and the lengthy telescope , over 2 metres long , had a limited field of view though the dome 's opening . A large stone pillar was constructed inside t... |

By the 1890s , the observatory had become crowded by the rapidly growing university . Electrification of the tramways along College Street just to the south , and the large quantities of metal used in the modern buildings surrounding the site threw off the instruments . A new magnetic observatory opened in 1898 in Agi... |
By 1907 , new university buildings completely surrounded the observatory ; dust from the construction clogged meteorological instruments , and at night electric lighting made astronomical work impossible . The Meteorological Office decided to abandon the site and move to a new building at the north end of campus on Bl... |
The university assumed ownership of the now @-@ disused observatory building and was originally going to abandon it . Louis Beaufort Stewart , a lecturer in the Faculty of Applied Science and Engineering , campaigned for it to be saved for the Department of Surveying and Geodesy . He eventually arranged for the buildi... |
In 1930 the Meteorological Office no longer used the Cooke telescope , and agreed to donate it to the university if they would handle its removal . Both the telescope and the observatory dome were moved to the observatory building . The telescope moved once again in 1952 to the David Dunlap Observatory north of the ci... |

The 1973 Atlantic hurricane season was the first season to use the Saffir – Simpson hurricane scale , a scale developed in 1971 by Herbert Saffir and Robert Simpson to rate the intensity of tropical cyclones . The season produced 24 tropical and subtropical cyclones , of which only 8 reached storm intensity , 4 became... |
The season officially began on June 1 , 1973 , and lasted until November 30 , 1973 . These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin . However , the first system formed on April 18 , more than a month before the official start . Three more depressions f... |

Later in August , Tropical Storm Christine became the easternmost forming tropical cyclone in the Atlantic basin on record , developing over the western African country of Guinea on August 25 . The system traveled for several thousand miles before dissipating in the eastern Caribbean Sea in early September . At the st... |
In late September , a brief depression affected northern Florida before dissipating . After a week of inactivity , the second subtropical storm of the year formed over the central Atlantic .

During its passage of Bermuda , Alice produced sustained winds up to 75 mph ( 120 km / h ) and gusts to 87 mph ( 140 km / h ) .

Already suffering from severe flooding that killed at least 18 people and left 200 @,@ 000 homeless , Hurricane Brenda worsened the situation with torrential rainfall and additional flooding .

On August 30 , the first reconnaissance mission into the storm found tropical storm @-@ force winds and the first advisory was issued that day , immediately declaring the system as Tropical Storm Christine . Three days later , Christine attained its peak intensity just below hurricane @-@ status with winds of 70 mph (... |
During its passage through the Leeward Islands , Christine produced torrential rainfall , peaking at 11 @.@ 74 in ( 298 mm ) in southeastern Puerto Rico . These rains led to flooding on several islands . One person was killed during the storm after being electrocuted by a downed power line on a flooded road . Schools ... |

Due to the erratic track of the storm along the Texas coastline , widespread heavy rains fell in areas near the storm and in Louisiana .
