Margarita Karovska:
I have the dates for the Chandra observations:
April 29 and April 30
For HST, the observations are being scheduled for the week of May 17th.
It would be wonderful if we can get some spectra during these periods.
Spectra would be very welcome during these periods, not easy, low altitude in the morning sky.
