Prikvačeni tweet
X8.2 flare from
#AR12673 was impressive. Coronal wave went past both poles. Big proton event, likely GLE. EIS must've seen plasmoid ejectionpic.twitter.com/lRgR6uEuIiHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
The silhouette indicates this is a presentation by Prof. Banerjee. I would have loved to hear his talk had my travel to India not been scrapped. Incidentally, Lindemann was "a brilliant but arrogant intellectual, who quarrelled sharply with many respected advisers." (Wikipedia)https://twitter.com/markcheung/status/1224312390000365568 …

Great opportunity to test models of how solar magnetic field extends into the heliosphere. This may impact our understanding of disturbances observed in near-Earth space (or 1AU) and beyond.https://twitter.com/NASASun/status/1220387807815970816 …

A nice eruption again today from the new (solar cycle 25) region that has not been promoted to a numbered active region. Clear dimming (and a bit of a large scale coronal wave), but I doubt the eruption will have impact on us. Another example of dimming not signaling a CME?pic.twitter.com/LCjoaJVLKh

NOAA SWPC forecast discussion issued at 2020 Jan 20 1230 UTC mentions this event. It refers to a B1 flare, but this comes from GOES 15 measurement, which is mostly background. GOES 16 shows A3.3. But GOES 16 data are not available on the X-ray flux page. Please fix this. https://twitter.com/halocme/status/1219134943701413888 …pic.twitter.com/XJUwCi6qsK

The recently-emerged solar cycle 25 region produced an impulsive eruption seen as a global coronal wave. The region is almost in Earth-strike zone, but I doubt this event will reach us. Incidentally, the region has apparently failed to be a numbered active region.pic.twitter.com/fX9MRIv9Uo

New region with solar cycle 25 polarity at N18. Let's hope this will get promoted to AR 12757. In the meantime, it produced an eruption with a spectacular large-scale coronal propagating front, which I am looking at now.pic.twitter.com/IsTIxEfl5P

There was a possibly Earth-directed CME on Jan 14, but it probably won't affect us. The animation compares running ( I(t_(i+1))-I(t_(i)) ) and base (pre-event subtracted, I(t)-I(0) ) difference techniques. The latter is good for long-last changes, such as dimming.pic.twitter.com/Cga6qwsl6F

X-ray flux data at https://www.swpc.noaa.gov/products/goes-x-ray-flux …. Diurnal variations are clearly seen. Flux in long wavelength (1-8 A, red) is at valley around 18 UT everyday. Short channel (blue) shows double peaks. How can these represent true X-ray flux? One needs to be careful at low flux.pic.twitter.com/J3w3qIrjwf

The CME that occurred on Jan 7 was a beautiful flux-rope CME (left: intensity, right: running difference, the movie credit to Kevin Schenk). No clear signatures in AIA EUV images, that is, stealthy. Or a far-side CME? We have no clue as to activity behind west limb (no STEREO-B).pic.twitter.com/N2KfQOerjY

The region that emerged yesterday was a new (solar cycle 25) polarity region at latitude N22. It should be AR 12756.pic.twitter.com/TeHgvDwaAh

Yes, I slowly understand the red and blues lines in https://www.swpc.noaa.gov/products/goes-x-ray-flux … represent data from GOES-16, which is more sensitive and accurate at low flux conditions. But are slow variations due to X-rays, unaffected by killer electrons?

Continued and calibrated measurement of the solar X-ray flux is very important for our everyday life. But the plot at https://www.swpc.noaa.gov/products/goes-x-ray-flux … does not make sense to me. Do red and blue really represent fluxes from GOES-16? We've seen this for a month.

If you look at solar images closely, you may find something unexpected. There was a large-scale coronal wave, not associated with a flare (and likely not with a CME) from a region that was not registered as an active region. A second eruption to NW may or may not be related.pic.twitter.com/eLM7aWn2W3
