[vsnet-chat 7178] Re: [cvnet-discussion] NSV 601 = New dwarf nova

[Mike Simonsen]

Good work Sebastian!
Sorry it took so long for a response. Been pretty busy of late.
I'll try to put to gether a chart for it and post it to the CVnet discussion
files section. Maybe this weekend if it's rainy.

Are you planning to do an IBVS or something on this discovery?
