Ancient teak log coffins found in Namjang (NJ) Cave, Pang Ma Pha district of Mae Hong Son province in Northwestern (NW) Thailand, were dated using a combination of C-14 dating and cross-dating techniques. The longest tree-ring width chronology...

If you want to explore how valuable different forecast schemes are in different operational scenarios, the data and code (python) are packaged up and available here
CME arrival time provides actionable information when false alarms can be tolerated Forecasting CME arrival speed increases the range of scenarios in which forecasts are valuable CME arrival speed sh...
Mathew OwensOne to file under "bloody obvious"?
Severe space weather (SSW) is driven by CMEs. But using CME arrival at Earth to forecast SSW is only useful if you can tolerate false alarms (not all CMEs cause SSW). Also predicting CME speed adds forecast value.
Visible coronal structure, in particular the spatial evolution of coronal
streamers, provides indirect information about solar magnetic activity and the
underlying solar dynamo. Their apparent absence of structure observed during
the total eclipses...
Mathew OwensThe solar eclipse of 1806 was during the most recent Grand Solar Minimum (GSM). Ezra Ames' paintings of the corona show the "solar maximum" state that modern models and reconstructions predict for 1806; solar cycles continue apace through a GSM.
Big news this week about the giant, burning, boiling, spinning thermonuclear reactor which lies 93 million miles away from Earth but is our primary source of life-giving heat and light.
Mathew OwensApparently I wasn't as effective at shutting it down as I thought.
At least the Mail spoke to me and Jeff Knight from the Met Office (who made a very sensible statement). Miles ahead of The Sun's completely unsourced article.
Local inversions are often observed in the heliospheric magnetic field (HMF),
but their origins and evolution are not yet fully understood.Parker Solar Probe
has recently observed rapid, Alfvenic, HMF inversions in the inner heliosphere,
