Supertyphoon Lekima and Typhoon Francisco approaching Japan

Supertyphoon Lekima and Typhoon Francisco approaching Japan
Typhoon Francisco is battering Minamidaito Island in Okinawa Prefecture, Japan. Super Typhoon Lekima is on a northwest path toward Iwo Jima and it is forecasted to turn away to the northeast in the next 48 hours. Maximum sustained winds are 140 knots (260 km/h, 162 mph) with gusts up to 170 knots (314 km/h, 195 mph)!  

Fukushima moves radioactive water as it braces for Typhoon Francisco
Japan’s Fukushima nuclear power plant is bracing itself for Typhoon Francisco, set to hit the country this weekend, by quickly securing new storage space for contaminated rainwater that has already taken up the facility’s entire storage tank capacity.  

Major solar flare measuring X1.7 erupted from Region 1882
Following days of increased solar activity newly emerging Active Region 1882 erupted with major solar flare measuring X1.7 on October 25, 2013. The event started at 07:53, peaked at 08:01 and ended at 08:08 UTC. This region is not in geoeffective position but will be in the coming days. Potential impacts: area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point. Radio - Wide area blackout of HF (high frequency) radio communication for about an hour.

CHANCE OF STORMS
Earth's magnetic field is about to receive a glancing blow from three CMEs observed leaving the Sun between Oct. 20th and 22nd. Forecast models suggest that the three clouds merged en route to Earth, and their combined impact could trigger a mild polar geomagnetic storm on Oct. 24-25. Solar activity is high. On October 24th at 00:30 UT, Earth-facing sunspot AR1877 erupted, producing a powerful M9-class solar flare.  

Zhupanovsky volcano (Kamchatka): new eruption
A new explosive eruption started yesterday night (23 Oct). An ash plume was detected drifting at an estimated 16,000 ft (5 km) altitude and drifting ESE. At least 1 mm of ash have been deposited in the Nalychevo valley, a natural park between Zhupanovsky and Avachinsky volcanoes.
