Incredible Skywatch Weekend: Northern Lights, Meteor Fireballs & Planetary Sights (Sept 27–28, 2025)

Key Facts Solar Storms and Aurora Outlook Space weather officials are on alert for auroras this weekend. A large coronal hole on the Sun has rotated into an Earth-facing position, sending a stream of fast solar wind toward Earth. According to NOAA’s Space Weather Prediction Center, this “weak enhancement in the solar wind” is forecast to arrive and push geomagnetic…

Northern Lights, New Comet & Saturn Shine: Must-See Sky Events on Sept 25–26, 2025

Northern Lights, New Comet & Saturn Shine: Must-See Sky Events on Sept 25–26, 2025

Summary Auroras Dance Under Equinox Skies It’s aurora season! The autumnal equinox (September 22) is traditionally a prime time for auroras because of the way Earth’s magnetic field interacts with the solar wind this time of year. Researchers have observed that around the equinoxes, cracks tend to open in Earth’s magnetosphere, allowing even relatively minor solar activity to trigger auroral…

  • Slide Insurance Holdings (SLDE) Shares Enter Oversold Territory on RSI Drop
    January 27, 2026, 5:33 PM EST. Shares of Slide Insurance Holdings Inc (SLDE) fell into oversold territory on Tuesday, with its Relative Strength Index (RSI) dropping to 29.7, just below the key threshold of 30 that indicates potential exhaustion of selling pressure. SLDE shares traded as low as $15.75, significantly below their 52-week high of $25.90, but above the 52-week low of $12.53. By contrast, the S&P 500 ETF (SPY) maintains a neutral RSI level of 58.9. Investors using RSI as a momentum gauge might view the current reading as a signal to consider buying opportunities in SLDE following recent heavy selling. This fits legendary investor Warren Buffett's strategy to be greedy when others are fearful.
