EVE Sounding Rocket Launch Update

Update on EVE sounding rocket from Tom Woods:

Based on continued unacceptable (red) wind conditions for Tuesday March 22 and very good weather conditions forecasted for Wednesday, the launch for NASA 36.275 is now scheduled for Wednesday March 23. That is, we have scrubbed plans to attempt launch on Tuesday.

The Wed March 23 launch window is the same as previously planned:
11:50 AM - 12:20 AM MDT (17:50 - 18:20 UT)

SDO EVE Calibration Rocket Scheduled for Next Week

There are 3 launch dates reserved next week for the SDO EVE Calibration Rocket (NASA 36.275). The weather forecasts are for unacceptably high winds on Monday March 21, but acceptable winds on Tue March 22 and Wed March 23. We plan to decide tomorrow (Thur 3/17) on whether we’ll give up the range for March 21 and only try for launches on Tuesday or Wednesday.

The launch window is 11:50 AM - 12:20 AM MDT (17:50 - 18:20 UT) for all three days.

Spring 2011 Eclipse Season Has Begun

The spring 2011 eclipse season has begun. Every day until April 2, 2011 there will be a short break in the data flow as the Earth moves between SDO and the Sun. The length of an eclipse can be as long as 72 minutes and they happen at about midnight at our ground station in Las Cruces, NM (0700 UT).

The EVE calibration rocket flight from WSMR is scheduled for 3/22 between 1800-1830 UTC.

EVE observes the recent flare activity

The Sunspot Number is 122 (at the time of this post) and there have been several M-class flares and an elevated chance of X-class flares. This plot from SDO's EVE investigation shows the increase in flare activity observed by EVE's EUV SpectroPhotometer (ESP).

AIA Data Flowing Again

AIA data is flowing again to the Sun Today webpage at LMSAL and The Sun Now on the SDO website.

AIA Images Unavailable This Weekend

The AIA NRT data stream from the JSOC-SDP to LMSAL has been shut down. SDO team members are running some tests over the weekend to isolate the problems with the connection between LMSAL and the JSOC/SDP. Most of these should be transparent to the community. However, the NRT data stream generates the data products seen on Suntoday, iSolSearch, Helioviewer, etc. The stream will be off overnight (pacific time) and will resume tomorrow morning.

In addition, The generation of AIA level 1.5 generation has also been stopped to help alleviate a data generation volume problem at the JSOC. The AIA synoptic images at http://jsoc.stanford.edu/data/aia/synoptic/ are still available.

SDO will observe a lunar transit today.
Here is a video illustrating the transit.
