SPACE PULSE

⚡ TL;DR
A multi-day geomagnetic storm sequence peaked at G2 (Moderate) on Aug 8 and a G1 Watch is now in effect for Aug 12, keeping space weather front and center this week.
The launch manifest is light but purposeful, with JAXA's QZS-7 navigation satellite and Rocket Lab's next iQPS radar bird both on the near horizon.
🚀 LAUNCHES
UPCOMING: H3-9 / MICHIBIKI No. 7 (QZS-7)
- JAXA has formally set the launch schedule for Quasi-Zenith Satellite System flight No. 7 aboard H3 Launch Vehicle Flight No. 9, announced 09 Aug 2026. [1]
- QZS-7 will expand Japan's homegrown precision-navigation constellation, which provides centimeter-level positioning augmentation across the Asia-Oceania region. [1]
UPCOMING: Electron / "The Lightning God Defends" (iQPS Launch 8)
- Rocket Lab's Electron will carry a synthetic aperture radar Earth-observation satellite for Japanese imaging company iQPS, with a current target no earlier than 31 Aug 2026. [2]
- The mission continues Rocket Lab's dedicated small-sat cadence for iQPS as that company builds out its commercial SAR constellation. [2]
☀️ SPACE WEATHER
HEADLINE: G2 storm struck Aug 8, G1 Watch active for Aug 12
- NOAA SWPC issued a K-index of 6 alert at 21:00 UTC on 08 Aug, placing conditions at G2 (Moderate) for the 1800-2100 synoptic period; a corrected advisory confirmed the same threshold. [3] [4]
- Prior to the G2 peak, back-to-back K5 alerts and extended K4/K5 warnings tracked a persistent, hours-long elevated geomagnetic disturbance throughout Aug 8. [5] [6] [7]
- A K6 warning valid through 23:59 UTC Aug 8 flagged onset conditions ahead of the confirmed G2 reading. [8]
- NOAA's latest watch (issued 13:38 UTC 09 Aug) supersedes all prior watches: Aug 10 and 11 are forecast below G1, but Aug 12 is expected to reach G1 (Minor). [9]
- At G2 levels, power-grid fluctuations at high latitudes are possible, HF radio propagation degrades at higher latitudes, and auroras can reach as far equatorward as 55 degrees geomagnetic latitude. [3] [9]
- A brief but notable solar proton event was recorded in the recent background: 100 MeV integral flux exceeded 1 pfu on 30 Jul, beginning 18:25 UTC and ending 18:30 UTC (5-minute event). [10]
🛰️ MISSIONS
JAXA QZS-7 SCHEDULE CONFIRMED
- JAXA's formal press release of 09 Aug locks in the launch window for MICHIBIKI No. 7, adding a seventh satellite to the Quasi-Zenith Satellite System constellation. [1]
- QZS-7 will ride H3 Flight No. 9, marking continued operational use of Japan's next-generation flagship launcher following its earlier certification flights. [1]
🔭 DISCOVERIES
NASA APOD SOLAR FEATURE — 09 AUGUST 2026
- NASA's Astronomy Picture of the Day for 09 Aug 2026 is titled "Contemplating the Sun," a timely solar image released as active geomagnetic conditions continue.
