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.
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.
