M1.7 flare from AR 4274 produced an asymmetric halo CME. The main propagation is toward the NE, with an Earth-directed component. Impact is likely around Nov 10th 7.11.25 Video Edward.Vijayakumar, with Jhelioviewer program x.com/edwanx/statu...

"Yet another eruption from AR 14274 with a nice coronal wave that strongly disturbed the lower corona. The associated flare was M8.6. With these eruptions resulting in halo CMEs, it would be very challenging to interpret the 1 AU in situ during 7-10 Nov." Halo CME x.com/halocme/stat...

Here is a video of the two large (X-class) solar flares on the Sun today. Where there are two, there are likely more to follow. We could be in for a busy week of solar activity! #spaceweather

The CME from the X1.8 flare in AR 4272: a clear, if lopsided full-halo CME! The bulk is obviously and expectedly going to the NE, but there is a clear full halo, meaning there is definitely an Earth-directed component. Jure Atanackov x.com/JAtanackov/s...

Two X-Flares today so far. X1.8 around AR 4274 in the northeast quadrant and just now, an X1.1 from behind the southeast limb. SolarHam.com

An X1.8 eruptive flare from AR4274 was followed by bright post-flare loops. The associated CME is directed toward the northeast. 📷 Edward.Vijayakumar x.com/edwanx/statu...

X1.8 flare that occurred just two hours ago. AR 14274 is still active, although I feel this one is a little less dynamic, globally speaking, than the earlier event from the same region. 📷 Halo CME x.com/halocme/stat...

The X1.1 flare from the unnumbered active region produced an awesome CME as seen here in a quick movie from GOES SUVI 195 Å. The CME is likely not going to impact Earth, although we may see a glancing blow at the most. Spectacular!

AR4272 and AR4274 remain highly active. Eruptive C8.8 flare from AR4272 followed by an M3.5 flare from AR4274. Magnetic complexity of AR4274 continues to increase, potential for further activity. Video Edward.Vijayakumar x.com/edwanx/statu...

Double eruptions from AR 14274 this morning. First M1.6 flare & then M5.0 from southern part of the region. Both showed nice global waves. But they did not reach Earth strike zone bec of the big coronal hole sitting just east of the central meridian. Video: Halo CME x.com/halocme/stat...

Imaging comet Lemmon on October 23rd. I was planning to focus stack the sky with the astro rig as it was shooting the comet. But then kind of preferred the soft focus sky with all the star color and Corona Borealis arcing beautifully at upper right. So indecisively posting both:) #astrophotography
