- The AAVSO and multiple astronomers request ongoing monitoring of the recurrent nova T CrB 1) to alert the astronomical community as soon as T CrB begins its eruption, and 2) to continue to build its multicolor light curve prior to, during, and after the anticipated eruption. Observations with all filters, as well as visual observations, are requested. Spectroscopy is also requested. Observations should be reported to the AAVSO International Database (AID) or AAVSO Spectroscopy Database (AVSpec) as soon as possible after making them.
- Frederick William I of Prussia (Wikipedia)
Frederick William I (German: Friedrich Wilhelm I.; 14 August 1688 – 31 May 1740), known as the Soldier King (German: Soldatenkönig), was King in Prussia and Elector of Brandenburg from 1713 until his death in 1740, as well as Prince of Neuchâtel. Frederick William instituted major military reforms, and expanded the army to new limits. He also made efforts to reduce crime and corruption in his state and centralized his authority during his 27 years reign, cementing Prussia as a regional power. His other notable decisions would be the selling of Prussian overseas colonies and the foundation of the Canton system, as well as the conquest of the port of Stettin. He was succeeded by his son, Frederick the Great.
