Happy #SunDay! This week’s space weather report includes: · 2 C-class flares · 1 M-class flare · 22 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory shows activity on the Sun over the past week.

The FAA has given license authorization for the second launch of the SpaceX Starship Super Heavy vehicle. The FAA determined SpaceX met all safety, environmental, policy and financial responsibility requirements. faa.gov/space/stakehol…

Really interesting week in Washington, DC 🇺🇸at the American Nuclear Society conference, representing Risktec Solutions Some great speakers focusing on new uses of nuclear technology in space. Also lucky enough to be asked to chair one of the sessions on Human Factors / Safety Systems.

Congratulations to the entire SpaceX team on an exciting second integrated flight test of Starship! Starship successfully lifted off under the power of all 33 Raptor engines on the Super Heavy Booster and made it through stage separation

Excited to be at #SpaceConference2023! 🚀 #UKSC2023 Visit us at booth D15 to discover the ground-breaking research we're doing and learn how we can support space SMEs. #Innovation #SpaceTech And see our facilities which SMEs can use: issuu.com/universityofsu…

Todays Sun - 184 sunspots visible! Lots of unstable filaments capable of producing CMEs. Taken in hydrogen/alpha 🔭 ☀️ Space Weather Watch SpaceWeatherLive Astronomy Picture of the Day RASC Calgary Centre

A total of 6 flights over the last week. Effective dose of these (GCR conditions) was ~60uSv. A sudden change in space weather could increase this to ~200uSv, (equivalent to 2 x chest X-rays) Surrey Space Centre research looks at #radiation #risk for high altitude flights IAASS Space Safety

Aurora forecast and #yyc cloud forecast tonight (clear)! 🤞

The sun went boom yesterday (don't worry we're gonna be okay). While I was shooting this sunspot group on the sun, one of them flared violently, yeeting planet-sized masses of plasma into space. The crazy part- this is a very small flare. They can get huge!

Interesting article on comparing terrestrial regulations for space environment. John Catchpole and I have recently submitted a paper looking at the current regulation of radiation risks for very high altitude ‘near space’ tourism flights. csps.aerospace.org/papers/space-s…

Some planetary observations last night with TÜV Rheinland Risktec work colleagues at the WCO. 🪐 and Jupiter also visible but no great images this time as super bright moon. RASC Calgary Centre

Solar observing today with RASC Calgary Centre and use of their telescope rental program for an additional hydrogen / alpha scope. Bit hazy 🌫️ ☀️ today but stable sun spots including AR3531 clearly visible. Not a bad backdrop / view of the Rockies 🏔️ either.

This week’s flight radiation data. Effective dose exposure from galactic cosmic radiation (GCR) using MAIRE (orange), SIEVERT (purple) and CARI-7 (blue) for flight at 36,000ft. Total effective dose exposure of ~10uSv, equivalent to a single dental X-ray. Surrey Space Centre #Risk

Looking forward to presenting at the NEI Nuclear Decommissioning Conference in California this week. If you’re attending, or in California this week, and want to connect on radiation / nuclear / risk assessment please feel free to reach out. #Nuclear #Radiation #Risk

Working with Space Lawyer John Catchpole, we’re delighted to have our research on the policies & regulations governing the radiation risks for space tourism flights, published in the LSE Space Policy Journal Surrey Space Centre University of Surrey doi.org/10.1016/j.spac… #Radiation #Risk

🗣️“There is very limited information given to them at the moment” Space weather expert Chris Rees is calling for stronger warnings about radiation risks in the space tourism sector 🚀 🎧Listen to 🎙️Tech & Science Daily 👇 lnk.to/x494eZ
