Comet McNaught, also known as the Great Comet of 2007 and given the designation C/2006 P1, is a non-periodic comet discovered on 7 August 2006 by British-Australian astronomer Robert H. McNaught using the Uppsala Southern Schmidt Telescope.[3] It was the brightest comet in over 40 years, and was easily visible to the naked eye for observers in the Southern Hemisphere in January and February 2007.
With an estimated peak magnitude of −5.5, the comet was the second-brightest since 1935.[4] Around perihelion on 12 January, it was visible worldwide in broad daylight. Its tail measured an estimated 35 degrees in length at its peak.[5]
The brightness of C/2006 P1 near perihelion was enhanced by forward scattering.[6]

STS-116 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Discovery. Discovery lifted off on 9 December 2006 at 20:47:35 EST. A previous launch attempt on 7 December had been canceled due to cloud cover. It was the first night launch of a Space Shuttle since STS-113 in November 2002.[4]
The mission is also referred to as ISS-12A.1 by the ISS program. The main goals of the mission were delivery and attachment of the International Space Station's P5 truss segment, a major rewiring of the station's power system, and exchange of ISS Expedition 14 personnel. The shuttle landed at 17:32 EST on 22 December 2006 at Kennedy Space Center 98 minutes off schedule due to unfavorable weather conditions. This mission was particularly notable to Sweden, being the first spaceflight of a Scandinavian astronaut (Christer Fuglesang).
STS-116 was the final scheduled Space Shuttle launch from Pad 39B as NASA reconfigured it for Ares I launches.[5] The only remaining use of Pad 39B by the shuttle was as a reserve for the STS-400 Launch on Need mission to rescue the crew of STS-125, the final Hubble Space Telescope servicing mission, if their shuttle became damaged.[6]
After STS-116, Discovery entered a period of maintenance. Its next mission would be STS-120 starting on 23 October 2007.

The original schedule of the torch relay in Japan was from 26 March to 24 July 2020. After the postponement of the Summer Olympics to 2021, all relays were delayed by 364 days (one day less than a full year to preserve the same days of the week), this is taken from the original 2020 schedule:
