Dear Observers,

Program stars in need of observation

The AAVSO maintains several lists of stars for which observations are strongly encouraged.  These are primarily stars for which the AAVSO already has well-covered light curves spanning several decades or longer, and for which we deem there is value in continuing observations indefinitely.

Binocular Sequence and Charts Now Available for Nova Del 2013

Due to the very bright eruption of Nova Del 2013, we have created a binocular sequence specifically for this nova that can be plotted using the Binocular Chart option on the chart plotter (VSP). 

For best results specify a field of view of 900 arc minutes (15 degrees) and a limiting magnitude of 7 and click on the Binocular Chart option. This will produce an uncluttered chart with a sequence from 6.9 - 3.5V for use with binoculars. Or you may simply download the chart attached to this page.

Dear Observers,

AAVSO Bulletin Generator

The following form will allow you to generate a customized copy of the AAVSO Bulletin suited to your needs.  You may select stars from a given constellation, range of Right Ascension and/or Declination, or simply type in a list of stars you would like returned.  You may also customize the page that's output by color-coding the months depending upon the brightness of the star, and also limit output to a single month.  Leaving all options blank will give you the complete list of stars in this issue of the Bulletin with no color added to the table.
