Guidelines for new solar observers

Guidelines for New Solar Observers

  • Do not look directly at the sun without the protection offered by a filter. For naked eye viewing, a piece of #14 welder's glass provides adequate protection. Do not use overexposed film, dark glasses, or other media that are not designed specifically for solar viewing.

Useful links for new solar observers

A vast amount of useful and informative material relating to the appearance of the sun at different wavelengths, visual and instrumental observation, and analyses and records of sunspot data are available via the Internet. The list below is intended to provide the new observer with some initial points of contact with this resource. Some entries in the list present the full address required to get to a specific display or table.

  • The NASA SDO mission released a fascinating video showing "rain" from a magnetic loop falling back onto the surface of the Sun.  It's not rain, but hot plasma magnetically levitated off the Sun!

Here are a number of solar photographs obtained by AAVSO solar observers over many years.  Thanks to all of the photographers for sharing their images with us!

 

 

Atmospheric seeing conditions for solar observing

Atmospheric Seeing Conditions

Contributed by Tom Fleming (FLET)

Reports and observations submitted to the AAVSO use the following ratings for atmospheric turbulence (Seeing): Poor, Fair, Good and Excellent.

An Observing Tale by Janet A. Mattei

How have you made your "friendship" with variable stars? Has it been through your observing? Or through your reading? Or through your training?

QX Pup

Update (July 7, 2015):  I-band coverage of QX Pup by AAVSO observers since 2010 clearly shows that the period given in the 4th Edition of the GCVS of 648: days is incorrect. A phase plot by Sebastián Otero of these data shows that the period of QX Pup in Ic is 551 days.

This is a multiple set of projects, so pick and choose what aspects of them interest you.
