- On 22 March 2024, a coordinated terrorist attack against civilians occurred at the Crocus City Hall music venue in Crocus City, Krasnogorsk, Moscow Oblast, Russia. The attack began at around 20:00 MSK (UTC+3), shortly before the Russian band Picnic was scheduled to play a sold-out show at the venue. Four terrorists associated with Islamic State – Khorasan Province (IS–KP or ISIS-K) carried out a mass shooting, as well as slashing attacks on the people gathered at the venue, and used incendiary devices to set the venue on fire. Investigators said 145 people had been killed (including those who died later in hospital), and more than 551 concertgoers injured by gunfire or suffering from burns. On 28 March, Russian authorities also claimed that a further 95 people were missing.
- Jordanus (constellation)
Jordanus (the Jordan River) was a constellation introduced in 1612 (or 1613) on a globe by Petrus Plancius and first shown in print by Jakob Bartsch in his book Usus Astronomicus Planisphaerii Stellati (1624). One end lay in the present-day Canes Venatici and then it flowed through the areas now occupied by Leo Minor and Lynx, ending near Camelopardalis. This constellation was not adopted in the atlases of Johann Bode and fell into disuse.
