The Occultation of a 13.1 by the Asteroid (45687) Pranverahyseni

Mar 19, 2022 at 10:10:57pm PDT

 

This event is special as it's a new name assignment by a friend of Ted Swift's who is an astronomy grad student at UCSC. The rank is low, so we'll keep our expectations low. Clouds are also likely to remain, as I write this at 4:30pm under solid clouds and occasional rain.

 

The rank is low, although Ted reported that residuals recently were tracking near zero, suggesting the path might be accurate.

Results:

A rare rain storm front passed through on March 19, and it remained wet and cloudy all day and my preliminary plans to drive to the upper meadow of UCSC turned into just staying home and keeping an eye on the sky. With 25 minutes before the event, the sky's clouds suddenly broke up and I did a mad dash to set up my gear in the driveway outside my place. I did get it all powered and aimed properly, although star field ID in this dense Milky Way field made it difficult for me. I did get a successful taping, with a couple of suspicious dips but which did not consistently reach to zero as would be proper, and also were outside the standard error limits. Kirk was also at home and had clear skies also and also got good data. Better data than mine, and his data showed no hint of any suspicious dips.

We're both reporting "miss"s. Rick Baldridge got sick and did not set up, and Ted Swift, despite a valiant effort to get to the centerline area on I-5, but was clouded out. Karl planned to try it too, but the storm clouds were clinging to his side of the mountain. No observation. The name-sake for this asteroid - Pranvera - is a PhD student now at UCSC after earning her master's, and is doing honorable work in helping foreign students as well.

Kirk Bender Results

Observed from home, and set his Watec 910hx at 8x. A miss was the verdict.
