Tropical storm Yagi forms in the western Pacific about 487 nm south-southeast of Kadena Air Base, Japan. Appears headed for Honshu, Japan.
Floods in Southern China
Heavy rainfall in southern China has claimed the lives of at least 15 people. Flash flooding has affected nine provinces in southern and eastern China including Anhui, Hubei, Hunan and Jiangxi.
Central European Floods
The floodwaters have reached Hungary where frantic defense work is underway. There is a sense of siege in the capital Budapest, where river levels are expected to be at their highest early on Monday. Forecasters say levels could rise up to 8.85m (29ft) – about 25cm (10in) higher than the Danube’s previous record high in 2006. In a worst-case scenario up to 55,000 people may need to be evacuated.

Near Earth Asteroids
Newly discovered Asteroid 2013 LR6, 12 meters in size, passed by Earth at only 0.3 Lunar Distances away on Saturday.
On June 9, 2013 there were 1397 potentially hazardous asteroids.
Notes: LD means “Lunar Distance.” 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
Every summer, something strange and wonderful happens high above the north pole. Ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky. Noctilucent clouds are a delight for high-latitude sky watchers, and around the Arctic Circle their season of visibility is always eagerly anticipated.
NASA’s AIM spacecraft, which is orbiting Earth on a mission to study noctilucent clouds, started seeing them on May 13th which is a week earlier than expected.
Noctilucent clouds were first noticed in the mid-19th century after the eruption of super-volcano Krakatoa. Volcanic ash spread through the atmosphere, painting vivid sunsets that mesmerized observers all around the world. That was when the NLCs appeared. At first people thought they must be some side-effect of the volcano, but long after Krakatoa’s ash settled the noctilucent clouds remained.
Novel Coronavirus – Update
The World Health Organization has updated its global count of Middle East respiratory syndrome coronavirus (MERS-CoV) cases to 55, including 31 fatalities, as Saudi Arabia reported another new case.
Bird Flu – China
No new H7N9 avian flu cases have been reported since the end of May.
Roundup of Global Volcanic Activity:
Pavlov (Alaska Peninsula, USA): Weak eruptive activity continues, producing small steam and ash plumes drifting at about 18-20,000 ft (5-6 km) altitude SSE as detected on satellite data (VAAC Anchorage).
Popocatépetl (Central Mexico): Given the currently low activity (1-3 weak steam and gas emissions per hour), CENAPRED has lowered the alert level back to “Yellow Phase 2”.
San Cristobal (Nicaragua): New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater. The new eruptions were followed by a rise in seismic activity in the form of tremor, which rose to about 3 times normal levels during the afternoon. The tremor pulse was still of relatively low energy and in itself not alarming, as the volcano experiences similar phases of elevated seismicity frequently, but given the recent activity, INETER warns that new explosions, possibly larger in scale, could follow with little warning and that air traffic should avoid the area of the volcano.
Cerro Negro (Nicaragua): The volcano might be entering a phase of reawakening. A seismic swarm of 49 low magnitude earthquakes and a pulse of volcanic tremor occurred on 4 June, INETER reported in a press release that day. The seismic activity started 08:45 am (local time) on 4 June, increased until 10:30 and the eased again. At the moment, the seismicity is calm again. No further reports have been published by INETER, who has not raised the alert level, but recommended to limit access to the volcano’s crater as a precaution measure.
