2019 AGU Fall Meeting Session SH009 -- High-Energy Solar Investigations Through Next-Generation Spectroscopy, from X-rays to Radio and beyond -- Call for Abstracts
by Amir Caspi 08 Jul '19

08 Jul '19

Dear colleagues, You are cordially invited to submit abstracts to Session SH009 “High-Energy Solar Investigations Through Next-Generation Spectroscopy, from X-rays to Radio and beyond,” for the 2019 AGU Fall Meeting, to be held in San Francisco, CA, 9 – 13 December 2019. Spectrally resolved measurements across the entire spectrum are critical for advancing our understanding of energetic phenomena on the Sun, during both flares and quiescence. This includes polarimetry and especially imaging spectroscopy, from X-rays and gamma-rays, through UV/EUV, to infrared and radio. To that end, this session invites presentations covering new instrumentation, enabling technology, missions, and concepts for next-generation solar spectroscopy, including spatially-resolved measurements, and the science that would be enabled by such new observations. The full session description and abstract submission are here: https://agu.confex.com/agu/fm19/prelim.cgi/Session/80247 The deadline to submit an abstract is Wednesday, 31 Jul 2019, at 23:59 EDT. We welcome your submissions to this exciting session! --- Amir Caspi and Lindsay Glesener

RHESSI Nuggets in June 2019
by Hugh Hudson 26 Jun '19

26 Jun '19

No. 353, “Localized Microwave and EUV Bright Structures in an Eruptive Prominence,” by Jing HUANG. Detailed correlations between EUV and microwaves in prominence fine structures. No. 352 “Broken-up hard X-ray spectra found for a loop-top source during a solar limb flare,” by Hao NING, Yao CHEN and Jeongwoo LEE. SOL2017-09-10 coronal hard X-ray sources. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting.

Free eclipse app for July 2, 2019
by Hugh Hudson 24 Jun '19

24 Jun '19

The free eclipse app "Eclipse Camera 2019" This is just a reminder that this app exists, both for IOS and for Android, and that it can be used to get valuable data from timing C2 and C3. The GPS capabilities of the mobile phones, plus the existence of the very precise Kaguya/LRO lunar data, should make this the most precise measurement yet of the solar radii. The more data the better, and so everybody is encouraged to let their mobile phone work on this effort. We are hoping for heavy redundancy to let us approach 1 msec timing precision in the mean. 1) Get the app "Eclipse Camera 2019'. Check it out and identify Equipment Settings -> Equipment "phone only". Locate the "Eclipse Image Capture" feature to be prepared. 2) Orient your phone so that the front camera sees the Sun. This can be quite approximate. Cover it to keep from overheating. 3) One minute before C2 (the app will tell you within a second or two, depending upon your GPS location), initiate Capture Mode and uncover the camera. The app will also provide an audible signal prior to C2 as a reminder. 4) Leave the camera alone to do its thing through C3. 5) When you return to Internet range, follow the app's instructions about upload. It is also possible to use an external lens with the app. One favorite one is the Huatop 20x (available on Amazon). This will take interesting coronal images and also resolve individual Baily's Beads. This is an outgrowth of the 2017 Megamovie program. See URLs eclipsemega.movie and https://eclipsecamera.com for more information. Hugh Hudson and Juan Carlos Martinez Oliveros
