Call for solar observations – 14-23 July 2016 – F-HUNTERS

For those who can't decide if there's not enough day, or not enough night!

*** WARNING ***

Do not EVER look directly at the Sun through a telescope or in any other way, unless you have the proper filters and have been educated in their proper use. This can cause INSTANT eye damage, and remember, you only get ONE pair of eyes!

Call for solar observations – 14-23 July 2016 – F-HUNTERS

Postby Flare Hunters » Sat Jul 16, 2016 2:55 pm


F-HUNTERS, the second solar flare observation campaign, organized by european consortium F-CHROMA, has just started. The main scientific goal of the collaboration is to understand physical processes that occur in the solar chromosphere during flares.

The campaign starts on 14 July and ends on 23 July 2016. The leading instrument used for observations is IRIS ( At the same time, several of the largest solar telescopes on Earth will perform accompanying observations. Amateur astronomers are asked to capture long sequences of images of the Sun, with intervals of about 10-20 seconds. Images saved in lossless format (such as FITS, TIFF, RAW, and not JPEG or PNG) have the most scientific value. Those images will provide more complete context of solar phenomena, in contrast to professional telescopes with extremely narrow field of view. Observations in chromospheric lines (H-alpha or Ca-K) are preferred, however we will also appreciate good quality white light images.

The current observing target is marked in the following chart:
