Subject: Re: HIGH CADENCE IMAGING CAMPAIGN: suggested dates Date: Sat, 27 Apr 2002 10:59:58 -0600 From: Alexei Pevtsov Organization: National Solar Observatory To: Richard Canfield Dick, Sorry for this late responce. I discussed our present capabilities for high cadence campaigns with Bala(subramaniam) and Steve Keil. Bala had to send you email in that respect, but apparently he did not. Anyway, we (NSO/SP) will be able to participate in high cadence campaign with our Flare Patrol full disk H-alpha telescope. Our usual time cadence is 2 minutes, but if this is necessary we can do 1 minute cadence. The only downside is that we still observe on photographic film, so the data should be digitize (which is not a big issue). In addition, we have live H-alpha images posted on our ftp server (1 image every 4 minutes) http://www.nso.edu/sunspot/latest_solar_images.html. However, these images are taken with TV-camera, so the resolution is low. Best regards, Alex -- Dr. Alexei A.
