Introduction

We've reached a milestone in SolarNuggets with this Nugget No. 500! The SolarNuggets began in 2005 with RHESSI Nugget No. 1, a description of the pioneering RHESSI hard X-ray and gamma-ray spectroscopy. A few of the earlier Nuggets have been lost, or no longer show their images properly. This just reminds us that digital archives have shelf lives, and may wither with time much as a First Dynasty [https://en.wikipedia.org/wiki/First_Dynasty_of_Egypt papyrus might. But most of them are there and many still have interesting messages; we're probably complete as far back as Eduard Kontar's Dentist Mirror classic.

Nugget history

These Nuggets arose from the Yohkoh Nuggets which themselves began as simple tohban reports in which observers report on remarkable operations in near-real-time. The most memorable Yohkoh Nugget, among many, might have been the triple jet item, a truly remarkable thing that has never been formally published, possibly because it shows actually inexplicable observations. The Yohkoh tohban reports morphed into the more informative Yohkoh Nuggets, which ran from 1997 to 2002; an AGU poster from 2002 describing them is here as a .pdf file (authors Hudson, McKenzie, and Nitta, the triumvirate supervising Yohkoh Nugget publication in those long-ago days.

How to do a HelioNugget

These articles are news-and-views opinion pages, not miniature scientific papers. Although, frequently enough, a Nugget-writer just wants to describe a journal article's great breakthrough. But any topic will do, as long as it is scientifically newsworthy, as one can see from the breadth of the topics, as linked by their icons on the home page. Here we see the last few icons...

Nugget future

There are now many Nugget series, plus other science-news sequences:

Yohkoh Nuggets
UKSP Nuggets
HMI Nuggets
CESRA Nuggets
Solar Orbiter Science Nuggets
...

These have different objectives, different styles, and different science specializations, but they are all great. The HMI Nuggets may be the most numerous, following the Yohkoh and RHESSI/Helio series.

To create a new HelioNugget, simply make a discovery, write a plain-text page of description, and send that along with 2-3 killer graphics, to hugh.hudson@glasgow.ac.uk.

As long as new ideas and discoveries appear, we must make them available worldwide!
