Marine Animal Disturbance reissued for South Africa after another airburst

2025, April 8. South Atlantic, 700km WNW of South Africa. Airburst. Coordinates: (32.2S, 10.4E). Altitude: 44.9 km. Velocity: 22.6 km/sec. Energy: e = 2.1, 0.076 or 76,000 kg/TNT. 2024-25 Ratio: 4:15. A marine animal disturbance is expected to be noted in southern Africa in the upcoming months.

This comes after the March 29 airburst in the Southern Ocean. Coordinates: (49.3S, 14.3E). Altitude: 21.6km. Velocity: 12.3 km/s. E = 5.9. -e = 0.19, 190,000 kg/TNT. 2,200 km north of Antarctica and 1,700 km SSW of Cape Town, South Africa. See Monday, 31 March post.

Comets and the upcoming risk for whale strandings

Two meteor showers will increase the risk of whale strandings in the southern hemisphere to high from the rest of July to September. The Delta Aquariids originate from the 96P Machholz comet and the 169P/NEAT comet created the Alpha Capricornids. These align to create a twin peak on July 30 with increased fireball activity, a rare event.
