Philalethes Posted February 9 Share Posted February 9 First LASCO imagery in already, definitely a big blast. Protons rising now too, right on schedule. Seems like ≥50 MeV and ≥100 MeV didn't move that much before going back down, but maybe that'll change depending on the trajectories. Link to comment Share on other sites More sharing options...

AlainSki Posted February 9 Share Posted February 9 x3.4! Was it on the limb or just beyond it? Wonder if the rating is fully representative if it was just beyond - that's one serious flare. Link to comment Share on other sites More sharing options...

Philalethes Posted February 9 Share Posted February 9 (edited) 15 minutes ago, MinYoongi said: how do you calculate the speed? Personally I grab an image from LASCO and use an online measurement tool to see roughly how many Solar diameters it's traveled, like so: Then I note the launch time, which seems to have been ~13:05, which means 1 hour and 13 minutes has elapsed since then in the above image. Divide distance by speed, and voilà, a rough estimate. That comes out to ~2160 km/s now, so the first estimate of 2900 km/s was probably a bit over the top, I just used the given value of 15 Solar radii per hour for that. It's hard to tell exactly though, could be higher too, but it's almost certainly at least over 2000 km/s in any case.

It traveled that distance in about 1 hour, so divide by 60 twice to get km/s. ................... There isn't really even a shock in coronagraph imagery to give us any chance at an arrival at L1. The CME looks fairly small, similar to the July 23rd, 2012 CME. Edited February 9 by Jesterface23 Link to comment Share on other sites More sharing options...
