5月10日起，二十年来最强的太阳风暴带来了一场持续数日的全球极光展，在欧洲，美洲，亚洲多地都能观测到。在美国，极光的可见范围南至佛罗里达州的迈尔斯堡。
美国国家海洋和大气管理局（NOAA）之前曾预告称本次太阳风暴将对电力系统、高频通信和全球定位系统产生影响。然而美国联邦紧急事务管理局（FEMA）称，到11日白天为止，辖区内没有收到任何高危报告。美国能源部也表示没有发现本次太阳风暴对电力系统有显著影响。
11日早间，SpaceX 公司称“星链”网络服务受到了影响，团队正在研究应对。公司CEO埃隆·马斯克前夜称该服务的卫星系统承受了不小的压力，但是目前为止顶住了危机。

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
