CSS_J014742.4+253431 - an RR Lyrae variable
CSS_J014742.4+253431 is an RR Lyrae pulsating variable of type AB (RRAB) discovered during the course of the Catalina Real-Time Transient Survey SNHunt on Catalina Sky Survey images.
A check at the time determining the nature of this variable showed this to be a previously unknown variable not in VSX or listed as such in VizieR. It was subsequently submitted to VSX.
Data:
Designation: CSS_J0147442.4+253431
Position: RA = 91h47m42.4s, Dec = +25d34m31s
Period = 0.511044 day
Range = 14.72-15.72CV
Constellation: Aries
Cross Identifications:
VSX J014742.3+253430
SDSS J014742.38+253430.4
Note: With more data available since the original release of the database, the above range and period are slightly different than that submitted to VSX.
The folded light curve was created using an Excel spreadsheat provided by Sebastian Otero of the AAVSO.
CSS_J033925.8+383925, a W UMa variable
CSS_J033925.8+383925 is a W UMa eclipsing binary discovered during the course of the Catalina Real-Time Transient Survey SNHunt on Catalina Sky Survey images
A check at the time determining the nature of this variable showed this to be a previously unknown variable not in VSX or listed as such in VizieR. It was subsequently submitted to VSX.
Data:
Designation: CSS_J033925.8+383925
Position: RA = 03h39m25.8s, Dec = +38d39m25s
Period = 0.381449 day
Range = 14.65-15.15CV
Constellation: Perseus
Cross Identifications:
VSX J033925.8+383926
SDSS J033925.81+383925.9
Light curve was created from an Excel spreadsheet supplied by Sebastian Otero of the AAVSO.
Range is slightly different than that reported to VSX.

Algol type variable CSS_J075804.5_250926
Via Flickr:
CSS_J075804.5_250926 is an eclipsing variable of the Algol type discovered during the course of the Catalina Real-Time Transient Survey SNHunt. It was discovered in the Catalina Sky Survey data.
A check showed this to be a previously unknown variable not in VSX or listed as such in VizieR. It has since been added to VSX. However, with additional data that is now available, the depth of the eclipse is larger than submitted to VSX.
Data:
Designations: CSS_J075804.5_250926 and MLS_J075804.6+250926
Position: RA = 07h58m04.5s, Dec = +25d09m26s
Period = 0.549096 day
Range = ~15.9 to 16.8CV
Constellation: Gemini
Cross Identifications:
SDSS J075804.56+250926.2
VSX J075804.5+250926
The above phase plot was created using the data from the Catalina Sky Survey (CSS) and Mount Lemmon Survey (MLS).
