A Night With A Few Variables

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.

High Energy Network activities in 2009

Activities of the AAVSO International High Energy Network, FY 2008-2009
 

High Energy Network Overview

The AAVSO International High Energy Network came about as an evolution of the AAVSO International GRB Network. The GRB Network was established at the First High Energy Workshop for Amateur Astronomers in April, 2000. The GRB network was a great success, detecting many GRB afterglows and discovering a few on our own. The follow-up of GRB optical afterglows continues to be a major focus of the Network today.
