紫外線が...などと呑気にかまえる状況ではないようです。
大規模な太陽表面の異常爆発「太陽フレア」が８～９日にかけて観測され、１１日には通信障害を引き起こす「磁気嵐」が発生するのではないかと報道されています。
Dr. Avellこと天文学者の阿部新助氏はＸで以下のように警告を発しています。
NOAA upped the Geomagnetic Storm Watch from Moderate to Severe for Friday through Sunday. This is the first Severe Watch in 19 years. That could grace the northern tier skies with auroras but also trigger GPS problems, hamper satellite communication and black out high-frequency radio.
The sun is crackling with sunspot energy, and two particular have roared to life.
NOAA has upgraded a geomagnetic solar storm watch from a level 3 ("moderate") to a level 4 ("severe") on Thursday as several solar flares hurtle toward Earth and are expected to combine. That could grace the northern tier skies with brilliant auroras but also trigger GPS problems, hamper satellite communication, and cause blackouts of high-frequency radio.
"Watches at this level are very rare," NOAA stated in the watch. "This is an unusual event."
This is the first "severe" Geomagnetic Storm Watch issued since January 2005.

文脈からも想像できるように「突進する」という意味の hurtleは勢いがかなり強い動詞です。
"to move very fast, especially in a way that seems dangerous:
The truck came hurtling towards us.
The explosion sent pieces of metal and glass hurtling through the air."
